drop brackets on an mj

will drop brackets for an xj work on an mj as well? control arm drop brackets that is. thank you

oh and are the leaf springs the same as well or no?

the drop brackets will work fine, you just won't be able to use the included reinforcements (don't *necessarily need them on an mj anyway-the lower arm mount is somewhat beefed-up to begin with) without reworking them a bunch. rear springs use a pretty different configuration, mj springs are quite a bit longer and are designed as spring under. so xj springs won't do you much good there.

For front suspension you can use pretty much anything from an XJ, but behind that it is different.
