Interest: A413 OBX/Quaife Spacers....

[Frank]

Would you be interested in a group buy that provdes the spacer and the fasteners to allow you to adapt a OBX/Quaife to a A413 style transmissions?

Provided the same combo works in a Neon "413" I am up for it.

[Frank]

It is supposed to work in any 413 based tranny... including the v6 and neon. I will verify that though.

[turbovanman²]

I could buy the spacer then save up for the diff, lol!

[Stevien1]

Build it! Build it! Build it!

Count me in for sure!

definately!

[BIG PSI]

I would buy one as well. Depending on when they become available I may buy two.

Thanks

Exactly what I was thinking. I am going to have my ho's work overtime so I can get a OBX. :whip:

I would buy one. Hey Frank, were you thinking of double bolting it? Or having long bolts go all the way thru the spacer? Just a thought. Might be alot stronger to double-bolt em... plus I've heard it's a PITA to find good fasteners for this application.

[Frank]

Myself and Cliff Ramsdell have been working this and we have the fasteners that require no modification at all. These bolts cost more, however they come out to the same cost of machine work because of the additional time it takes to make the extra holes, etc.


Frank

[contraption22]

But don't you think that using a long bolt like that could be a weakness?

[Frank]

Not at all. I would say yes if there were alot of twisting play, but there wont be. Each bolt whole will be no bigger then nessecary, and in addition, this adapter almost needs to be pressed on to the diff carrier and then the ring gear on to it. The trick will be to freeze the diff carrier, oven the adapter, put it on, then freeze that and oven the ring gear. Bolt together and walla.

The longer bolts are not a problem when there is not play. Even with the slopier fit, Carl never had any problems with his. I think this will be A++.

31TH, 404, 413, 670, are all the same diff. (any 3-speed FWD Mopar trans.) The only difference is when the big axles are used starting in '87. I use the 24 bolt spacers with 7/16"-20 threads in the spacer. With ARP bolts with the small heads, it requires little grinding on the case.

[David Bohrer]

I would like one!

your not putting chevy parts in your car are ya????

[John B]

Were there any of these that went unsold?

[looneytuner]

Contact T2Shadow for the spacers and needed bolts. he ran some on Cad equipment. For the spacer and bolts, it was under $100 shipped. For better Belleville washers for the OBX contact Rbryant. $15 shipped.

[turbovanman²]

The quality is unreal. I have one of his spacers, top notch. :thumb:

Thanks Simon. I'm shadow t2 on TD.com Currently out of spacers, but I might make another run of them. I'm just trying to guage how many(qty) to make for the next run. If Frank & Cliff already have it covered that's cool too.

[Frank]

We never got any made... been busy and we could never get enough interest to keep the machining within reasonable reach.

[turbovanman²]

Coy

If you really want to make some more, do a poll in this section and you can figure out how many if any, are to be made.

Well if you post in the thread I made in the Neons.org forum, I bet you could safely do another 15 unit run.

Frank

[DBB mini]

Thanks guys. I'm not really itching to run them at the moment as the mini has my hands entirely full. This winter however would be a great time for another run. I'll probably be runnin lots of government jobs at the shop anyway, as I may attempt the 16V stratus head swap including brackets, etc to TRY to keep my A/C. Picking a head complete upper half this weekend with cams, intake,exhaust, etc. for $50.00. Like a sore dong, hard to beat.

Coy

[rt1092]

I'll take 3 or 4 if someone will do them.

[rt1092]

I need one soon or I'm going to have to get it machined for myself.

[Frank]

I am going to reattempt to do these after thanksgiving maybe... dont know.

New to the group,

I'm an engineer, and in my new position with a company I just got hired on to, I have access to the entire shop. I would be interested in thickness that the spacer needs to be, because I have an A413 tranny, and I bought an OBX, and need the spacer. The tanny is going into a 1994 Sundance. The 2.2L has bad rod bearings, and I repalcing that with a 2.5L. I am using this vehicle over the winter in place of my 2005 Neon SRT-4, that I do not want to even attempt to drive in the winter here in Central New York.

If someone could tell me the thickness of this ring gear spacer, and if there is an Interest for several, I could have a small batch run off made out of steel. The steel material is dependant on thickness, though.

I have several options of cutting the material, but I am tending toward the laser as it leaves an "okay" finish, but depending on the final finish, I will either leaving it as such, or doing a final reaming on bolt hole pattern with only a minor touch up to the inside and/or outside edges.

In either case, I could really use the thickness, because I intend on getting this tranny back into the car by the end of the month...

[powermaxx]

I'll be needing one also so if this actually goes thru give me a shout!

And the sooner the better. :thumb:

Where in central new york are you? I am in Rochester, and my father owns a performance tranny shop in Syracuse. We may be interested in a couple of those spacers if you make them. My dad is building a 413 now with a phantom grip, but we may switch to the OBX for the next one if we can get a hold of the spacers.....

[james_13021]

I'm in Auburn, New York, but work in Syracuse, right by Carousel Mall. I also run a design company, called Nemo's Design (no web page).

But if someone could step up with a thickness dimension, I could have a large batch made out of steel in couple weeks. Again, depending on the thickness, they can be made out of anything ranging from 1040 to 4340 steel.

I don't want to put a price on them until I know the thickness.

The laser cuts a real nice finish, with only moderate need for touch up.

[rt1092]

Keep me informed I'll probably use 3 or 4 of them.
Thanks

[james_13021]

Well peoples,

Got the dimension needed for the OBX ring gear spacer. I had to pull a stock unit out and and OBX unit, and do a work up on them to gauge out the necessary thickness needed. I ran it through my 3D CAD tool, Autodesk Inventor, and got a nice model and drawing of it. I will see if I can't get a run on them within a week or two max. Just depends on production scheduling.

For those interested, I plan on making between 10-16 pieces, depending on how many will fit on a 48" square sheet...

[Frank]

Bravo man. I just was way to busy to do anythign about it. Here is the design I had.

http://www.turbo-mopar.com/temp/top.jpg

http://www.turbo-mopar.com/temp/bottom.jpg


The lips would allow no play of the ring gear to the spacer, and the groove ont he bottom of the spacer would allow no play on the carriage. Bolts would have to be special so you dont end up with 24 bolts. as I dont like having the spacer carry all the load unless it is made out of steel, but then is heavy.

DBB Mini's are steel.

[turbovanman²]

DBB Mini's are steel. Why doesn't someone PM him, I am sure he was the drawings on file.

[Ground Rat]

I need one.

[4cefedomni]

i also need one if anyone has one or is gonna make some please PM me

[Frank]

I gave up on them and passed my data to someone else to make them for cheap.

[james_13021]

I have several spacers, for $110.00 each. includes shipping. Moving must sell. (Steel)

email me: james_13021@yahoo.com for info.

[guhfluh]

Anyone still have drawings for a spacer?

[turbovanman²]

Did you get an answer?

[guhfluh]

Did you get an answer?

No answer. I found some "drawings" that were missing some specs, but really just ended up making a 1 off steel 24 hole spacer from measurements taken off the OBX and stock diff.

I tried replying to this a while back, but the forums were down...

[fixit]

found the measurements from "Custom Neon" here http://forums.neons.org/viewtopic.php?f=48&t=241456


The outside diameter of the lip on the differential is 4.555" which is roughly 4 9/16".
The lip on the top of the spacer should match that of the lip on the differential. (4.555" or 4 9/16")
Inside diameter of the bottom side of the spacer should be 4.658" or roughly 4 11/16" the spacer should fit snugly around the lip on the differential. Not to tight as to not be able to turn it to line up the holes but tight enough so that it won't slip off when you invert the diffreential.
The inside of the top lip should be 4.008" or roughly 4 1/16".
Overall thickness is 1 7/32 is actually 1.2188 (height, top to bottom).
Easiest way to start it is get yoruself a piece of thickwall black pipe about 6-7" in diameter with a 3 - 3.5" hole in the center. Then have it milled to spec.


I used to have pictures of mine with all the measurements but I've since lost them. Eventually I'll have the differential back out of it so I can take them again, but it's not going to be for a while yet.

[guhfluh]

That's basically what I has to go off of also, but it's still missing some measurements, like bolt circle.

[fixit]

what material did you use?

i was going to buy this aluminum 6061 dia=6" length 2" rod (~$25) and cut it down

[guhfluh]

It's steel, because we did a 24 hole spacer. I'm not sure exactly what material it is, as I'm not the machinist. I left that to my uncle who did it for me. We did the 24 hole because it was much easier to source shorter or factory bolts that we know would handle the load. And it was cheaper to get the shorter or factory bolts than the long ones. I wasn't worried about the little bit of extra rotational weight it adds and much more comfortable with the strength.
