I have ordered new stainless steel bolts to hold on my fiberglass fenders on my 83 step side, but I am having trouble removing the factory bolts. Any suggestions?

 

Welcome to FTE

Maybe this pic will help. Body style 83 is a Flareside pickup. A step side is a Chevrolet.

 

The original bolts "bite" into the sheet metal. To get the fiberglass fenders off, set your ratchet to tighten them and snap them off.

Then get a socket with the opening BIGGER than the heads on the inside, put the socket over the head and slam them out from the other side.

I'm doing this right now to on my 84 Flareside.
Or if you have a blue-wrench heat the steel, and the bolts "pop" out with a light tap.

 

Thank ou. This makes sense.
