All transplants I've done involved lengthening and shortening the drive shafts.

Most important is the they don't come off the splines or bottom out and wreck the Transfer Case .

Collapse the springs and measure the distance. Extend the springs and measure. I use a High lift for both measurements.

Then check against your current drive shafts. Local driveshaft shops can cut and weld.

I highly recommend Tom Wood's. Great service and they know Jeeps.
