4.0L Donors for 4.0L YJ

I just got the call from the shop: connecting rod came apart, and there's a new hole in my oil pan. I'm having a hard time finding a list of acceptable donors to put another 4.0L into the YJ. I need it up and operational as soon as possible, so a V8 swap is out of the question, and I can't afford a reman. I'd imagine '91-95 YJs would bolt in, and I've heard '91-95 XJ motors are similar, but I don't know if they're the same.

'93 YJ Wrangler, 4.0L, auto (32RH), NP231

Thanks in advance.

The block from a 4.0 from 91-2000 is the same and you can reuse all your upper end stuff. The only thing that becomes an issue is the temp sensor in the rear for the guage was combined in the later blocks so you need to port another location which is pretty well documented on the forum on where and how.
