I'm trying to replace the engine mounts on my 91' firebird engine is out of the car so topside access is no problem but I didn't realize that there was a nut on the under side holding it all together. Any suggestions on how to hold that nut still while I loosen the bolt and be able to get it back in there to bolt the new mount down? I thought I'd ask before I pull the spring out to get access to it.
I check other threads and found one, somebody suggested some swivels on the socket wrench and extension, but that thread was 6 years old, not sure if anybody as come up with an easier way.
