Default #3 Body Mount

Trying to remove body mounts on my 1976 Stingray. #3 bolt seems to just spin. Any recomendations?

Welcome!

(they are a b****)

For my #3, I took a pneumatic cutoff wheel and diced and ground the head of the bolt until I could knock it off. It's tight in there which makes it even more difficult. Pretty sure it's the best way to go though..

Most of the time this is rusted solid. You could try and stick a long drift between the spinning nut and the inside of the cage to hold the nut from spinning. The cage may be rusted as well and not be able to take this abuse. This is probably a long shot.

I found it easier to remove the fiberglass piece that covers this mount to give extra working access.

Other than this "slice and dice" the head bolt is the only option.

A very difficult one to remove. I had much success with the Dremel tool attached to a 90 degree bend attachment and a cut of wheel. You will need a pack of the wheels. Every thing came from Lowes. Good luck

you'll probably want to buy the cages since yours will most likely be in rough shape . They need to be welded on.

A die grinder, bigger badder and just way faster, use a rotary file!
