Boys - I’m getting close to installing a 700R4 in place off my 350TH. I’ve measured both transmissions and the 700 is about 3” longer. The existing driveshaft in the truck is a split with hanger bearing that I want to keep in case I want to change back to the 350 someday.

Should I just have a new single shaft made up for this application? Or should I find another primary shaft and have it shortened to work with the existing split setup?
