The studs thread in like the bolts do, and they will come out there. Spray the heck out of them with PB blaster for a few days ahead of time. One of mine was so stuck in there, it ripped the weld on the threaded insert. :swear_mad:
I have my original RE t-case drop somewhere in the garage, but it's missing one bolt and one spacer. Simple to duplicate.
It's yours if you want.
