Question on body mounts...
I need to replace the 2 rear sheet metal body mounts (the ones that are rivited to the body) due to rust. When I removed them from the body there appears to be something like a filler or adhesive in the pocket of the old mount. I will admit it may be compressed and petrified rust but it appears solid. I put a hand drill to it to see if it flaked off but it seems to be like ceramic.
Any idea what I should use as a filler/adhesive before I re-rivit the new mounts on? I could imagine it could be a source of squeeks.
TIA

There wasn't any filler under the reinforcements on my 72 when I removed them. If you have a pre-73 the hard material might be what's left of the solid body mount. My mounts were corroded and falling apart and didn't look much like aluminum any more.

It may be an adhesion compound (like Vette-Bond) that was used n conjunction with the rivets. I saw remnants of that on mine as well.
I replaced mine without the compound.
Note the top outer rivets had to be installed from inside the car.
No way to swing a hammer in there, so pop-rivets were used.

I just tuned into this thread while trying to find out what other members used to fill the gap between the metal body mount and the fiberglass.
I am replacing my mounts are well and notice the information about using pop rivets in tight areas where a hammer cannot fit.
I am using a tool bought from Harbor Freight but other places like Home Depot and Lowes but larger tool companies might sell them also. It is an impact "nail gun" palm nailer! I put a makeshift "rivet tool" into the end of the nailer and use that to flatten the soft aluminum rivet.
Hope this helps next time you run into a tight rivet area.
May I ask if you used a sealer or added the bonding adhesive before riveting?
