Is it one of the bolts that hold the differential to the frame, or it is a bolt that holds the rear monospring to the differential? Im not sure how hard it is to change the bolt. If its just a bolt( with a nut), go to a hardware store and get a new one. If its a bolt thats screws into the rearend, if you cant grip it with a visegrip or wrench, get a bolt extractor. You drill a hole in the bolt, and screw the extractor into the hole you drilled. You screw it in, the extractor is reverse threaded so as you screw it in (like your loosening a bolt) the extractor digs in and pulls it out. They're pretty cool. They work almost every time, the only problem is gettin the drill in there. Depending in where the bolt is, you might have to move some things out of the way. Hopefully you wont need to remove the monospring, thats where it gets time consuming.

Pretty common for the diffrential cover to crack at the spring mount. Get a heavy duty one Muskegon Brake

You don't really need the "heavy-duty" cover; 99% of them that have an ear broken off are that way because the last guy who installed a rear spring didn't follow the Shop Manual procedure and torqued those four bolts with the car up in the air instead of just snugging them, then torquing them with the car on wheels. :eyerole

I won't say yes, BUT I drove my 11Kmile white 79 home 1000 miles after purchase only to put it up on the hoist to find one of the 4 polts missing! Nothing broken but who knows when over the last 27 years it fell out? Mike.....yikes!

Yeah it's a common problem as John said of not following procedure on loading the rear spring. I have used the HD covers a several jobs and they are a quality product so it comes down to buying a used original or new muskegon- about $50 difference.
