I need an aluminum Shaft for my 91 stang and I dont know what length I need. I have a UPR chromoly K member in the car and I am using the rear mounting holes and I have a Powerglide. Thanks for any help..
You really need to get under the car an measure from the end of the PG output shaft to the pinion flange. I just went through this process. Think mine ended up being 51 1/2" measured that way. I had a local driveshaft shop build me a 3.5" aluminum shaft with 1350 U-joints...was about $400 total.
