I have a rebuilt 413 that I believe is an 86. It was in a 86 GLH-T and the guy I got the parts car from said it was a HD rebuild for racing. (He also said he ran high 11's on stock turbo, so who knows). Any way, I need a new (temporary) tranny in my turbo van untill I'm ready to swap in the 5-speed. This tranny has smaller splines and the diff (on the driver side) is recessed in about 2 " more than the current trans. I was wondering if I got some axles from an early Caravan (small spline) could I use this tranny?
