1985 D150 SWB 904 to 727 swap, need driveshaft length!!

If you just need a drive shaft, look into getting one made. I was shocked at how cheap it was. I used a drive shaft shop in Springfield, Missouri, and they told me how to measure it, they did the rest and at the time (ten years ago) it was under a hundred bucks to modify my existing drive shaft.

Iirc they recycled my ends and grafted them onto a new tube.
