rear driveshaft length. yes, another one

[JeepcoMJ]

what is the rear driveshaft length for a shortbed, automatic (AW4) 4.0 MJ?

 

then, Smitte, can you measure your rear driveshaft. I'm not sure how to measure shaft length so hopefully someone here will tell us how.

 

EDIT:

 

this is a 4wd equipped truck (or will be when I'm done)

when i measured for my solid axle nissan it had a slip yoke i measured from the output of the tcase to the back of the yoke on the axle. driveshaft shop did the rest.

 

i used string to get it dead on.
