The rear springs are 3" longer then the front springs (I think, you might want to measure that to be sure) so some modification is needed. For the RUF I built a set of folding shackles for the front end then put a 1.5" spacer on the driveshaft. Then we had to move the shocks forward a couple of inches so they squared up properly so I switched to the Ford Shock tower at the same time.
For doing as little work as possible, I would move the rear spring mount back half the distance and use a longer shackle to make up the rest in front. That way you gain a bit more flex but don't have to move your shock tower or put a driveline spacer on.
If you are looking to do a YJ conversion anyway, I would just save up and do that instead.
