As you guys know, i am not a VC dealer. I have a customer that has no idea where to get a replacement catalyst, and also has a frozen bolt holding the cat plate in. Any tricks to removing the bolt? And where is the least expensive place for them to buy a replacement. They think its about 20 years old. They will be checking this thread later. Thanks. I can order one from woodmans for them, but i have no idea what size it is.
