Very noticeable clunk going into reverse, crossmember mount is good, as well as motor mounts. Any suggestions?

U-Joints

Rear u-joint is good and the front trunnion is good.

This has been talked about to no end in recent months. If you have an open diff, the most likely place to look, is in the spider to side gear backlash. The clunk could be sorta normal . Or it could be a sign of nuclear explosion back there. Or it could just be u-joints,lol.
In any case, I would look into it asap.
You didn't take the cushion spring outta the hi-drum did you? That would be the front clutch in Mopar-ese.

watch driveshaft when your buddy goes into gear. If it moves, its rear.
