Who here is the A413 Guru?

[rdnoel86]

There is a weird back story I don't want to get into about the group buy I was involved in. My suggestion is if you are really serious about upgrading your trans, contact Boots directly. It would probably be easier for you to contact him through Facebook. He has some great new parts coming out also, pretty exciting stuff if you race the a413/31th You might see some of the parts following The Red Sleds Facebook page also...

Are you using the 904 input shaft? That is tops on my list of 413 upgrades. 904 300m input shaft and have your converter modified to accept it. Pretty indestructible.

No. From my understanding, it's an input shaft based off the 904/300m and is not hollow and can't be used with a lock up converter. I have a lock up converter and since my van is 99% street, 1% race I'm not willing to give up the lock up function. If I am wrong please correct me and also the year/make/model that this trans came in and I can get one probably from Transtar. Having my converter modified is not a problem. I need the year make and model because the 904 is RWD and the 300M is FWD so I don't know what to order it out of.

300M is referring to the material of the shaft, 300 maraging steel.
