TJ Pitman Arm Leak

While my TJ is up on jackstands waiting for a reverse gear to arrive...

I saw the other power-steering post, and it reminded me of my own leak.

I've got a slow leak (1.5" diameter mark on the floor overnight) that
appears to be coming from the steering box where the pitman arm
connects. After a google-groups search, it looks like a lot of
steering-box seals were bad in the early years of the TJ.

My question is, am I looking at a complete rebuild? Is there a seal
that is common to this problem that is easily replacable?

Thanks in advance..
