For those wondering what is being referred-to:
41-55 firewall retainer clips - image below
55-72 firewall retainer clips - image below
I could not load the images because I was incorrectly informed be the stovebolt.com Attachment Manager that the 38 kb file is too large - oh, well.
Here are links to the images:

https://www.classicparts.com/images/42-087.jpg (55-72)
I think the original post was referring to the 55-72 style plastic clip?
I'd warm up the 55-72 plastic clips and then try to hammer/punch them through (but, I have never tried to do so).
