Here's another firewall grommet question for all the folks that know more than I do.

I'm in the process of deciphering the wiring and instruments in my '48 1/2 ton chevy truck.

I have a grommet with 4 small holes (throttle,choke, temp?,oil?) but I seem to be missing the small oval plate that secures it
to the firewall. Are this available from any vendors that you know of?
Thank you
Jeff (slowly pulling my hair out putting this truck back together)
