Non-diagonal split Proportioning Valves?
Does anyone know some donor applications for converting from the stock diagonal split Proportioning valve to a Non-diagonal split valve?
This would be on the S-body (minivan SWB).
I considered a Wilwood unit, but can't seem to find one with metric threads.
Thanks.

Stupid question but why metric threads ?

Stupider question: aren't the stock threads metric?

Some of the ABS stuff has metric threads. Most all of our stuff is 3/8-24 and on the prop valve there are two 7/16-20 ports to prevent someone from installing the valve backwards.

Well great! Here I was thinking it was metric. I didn't do the brake line replacement, my brother did that for me before I ever picked the van up years ago.
Maybe that Wilwood I was looking at with the adjustable rear proportion would work.
Thanks for that info!

Thanks.
the stock threads are standard.
i said ---- it and took both of the master cyl outputs and plumbed them into a single line and then split it off into two lines.... one to the back with a wilwood adjustable proportional valve and one to the front with full power braking.
the car is not a daily driver and i can turn the rears down alot more than the stock prop valves will do.
when bedding in the pads, i let the fronts fade till the rears locked up and then backed the rears off a bit. i dont have end swap issues. i also meticulously maintain my lines and hoses and make sure my e brake with lock the rears.

Thanks Brian.
One thing that is on my to-do list is install some linelock solenoid, and I'd like the diagonal split to go away.
Here is the valve I was looking at by Wilwood. And it is on sale through Prime!

that unit looks great.
and is probably better than my setup. i looked under the hoods at lots of car shows and saw only one master cyl output on many cars and decided that it was good enough for my setup. that was 15 years ago lol.

Note that there are now hydraulic handbrakes that can run 2 lines.
