Struggled with this...so I made myself up a tool to do the dirty deed.

Those GM firewall pad holding grommets are a PITA...

This is the tool I made up to push those puppies in place, replacing a pad in my neighbors 63' C-10...not pretty, functional.

I used a 1/4 stove bolt, a 1/4 fender washer, a washer for an old shock, and a barrel nut (1/4 X 20)...the spot welds are just for holding it all together.

I also used it this way: I adjusted the stove bolt so that it would be slightly longer than the grommet, heated up the grommet with my heat gun, tapped it in with a rubber hammer, then finished driving it home with a 17mm 3/4 socket and 12 inch 3/4 drive extension.

It worked...for this old guy!

Not sure how the shock washer plays into the grand scheme of things :confused0006:

It provides a perfect surface for the grommet as the head is concave...as is the washer. It spreads the load lets say...a flat washer would only contact a little surface. Plus it can take a lickin and keep on driving without bending like a fender washer will.
