Driveshaft Length
Ok so I am working on my ZJ and discovered the front drive shaft will not work for the rear as a replacement after I put the lift and a 231 with a HNT flange on.
So I am now looking to get a replacement I know I could talk to Tom or Adam about their stuff but I'm Canadian and that would just cause a lot of issues on its own. So I hope maybe we have some experts on the matters in here and could give me an idea of what I need to do.
So from flat of flange to center of cap on the rear pinion I am looking at around 38.5" but where my question comes in is that there is a double cardan on this so that would be 38.5" extended and if you subtract the double cardan... say 3"... that leaves you around the 36" mark.
So would I need a driveshaft that is 36" compressed? Or 38" extended?
Thoughts? This whole driveshaft stuff hurts my brain.

I think the HD driveshafts (Adams, Tattons, Tom Woods, Etc) all come with extended splines.
I would ask them because all they do is build driveshafts for Jeeps and would probably know. Most of them have instructions on measuring for a custom DriveShaft.

But their measurements and how things work does not allow me to understand how things work :P
I understand the measurement is what you need for OVERALL length.. but does that mean fully collapsed or extended? OR how much spline shaft sticking out etc.
