Firewall pad plastic plug removal

[70post]

The Abody GM cars, at least '69-72, seem to use a soft plastic firewall plug with circular "barbs" on the shaft part that gets pushed through the pad and firewall.

The originals were somewhat flexible. Many of the repros are a harder plastic than the originals and tend to snap or break when you try to install them.

Don't know if anyone makes REAL NICE (somewhat flexible like the originals) repros of these or if all the vendors sell the harder plastic repro version.

I bought a box of Auveco brand firewall plugs for my '70 Abody cars MANY YEARS AGO and they appear to be the somewhat-flexible version like the originals.

Also...some of these harder plastic repros seem to have a slightly different finish or sheen to the plastic compared to originals.

I think the originals may be made of polypropylene plastic (the 69-72 GM Abody style I am discussing here).
