Here's the deal...I got a 90 Wrangler that has been lifted and converted from a 4 cyl to a V8 using a 700R4 and an S10 transfer case. The front driveshaft is missing.

How do i figure the proper lenght for a new one? When I look this up in a Jeep catalog, they list 2 lengths - one for the 4cyl and one for the 6.

Well...this being a V8 conversion with a 3" suspension lift levase me stumped!

I can easily measure the at rest lenght U-joint center to center, and jack it up to let the suspension extend and measure that. Not sure how to compress the suspension to measure that?

TIA
