I'm hoping someone can give me some advice. I've got a frozen filler bolt on my 54's differential cover. It has a square head, and appears to be 3/4". I tried the spanner and various pliers with no luck. Is heat my only other option? I don't have an oxy-acetylene torch, but was hoping to get by with one of those mapp-gas torches you can get cheap at my local hardware store. Will that give me enough heat to loosen things up?
Also, I'm thinking a "double square" socket would be nice to have--or a big pipe wrench. Surely someone else has had this problem before. I did find
one vendor the sells the bolt , so drilling it out could be an option. Thanks in advance.
