As soon as the car hits my driveway Im going to crawl under it and take a look at the housing to see if I have some numbers I can use a reference.
As soon as I explode that trans though, I wont be rebuilding it. I'll probably move to a ZF6 or 6060.
Best idea would be to go ahead and get a new trans, pull that one out, it's worth $$$ to the right collector.
