Measure the space between the axle and the frame bumper, and use this distance for the back end of the driveshaft. Make sure there's clearance from the rear u-joint to the front one in a straight line, and you're set. If you haven't got bumpers yet, reverse the procedure, use the driveshaft clearance figure to limit rear end travel. (Allow a bit more room for rear axle "wrap" on acceleration.)
Just remove the springs from the coilovers and install them back on the car. If the rear end can travel it's entire range of motion with the coilovers sans springs installed, everything is fine. You will not have near this much travel with the springs on the coilovers.....
Dave, you sound like you've done this once or twice b4. :D :D :D
