Never tried it, but I've read a penny works good as a backup plate with a
MIG welder. I've warped stuff by grinding on it, the thought of grinding off
an entire electrical box plug doesn't sound too good.

A round knockout metal plug from an electrical box works fine as a back-up
plate for small holes. It gives you something to weld against. It also makes
for
lots of grinding if you want the back side finished.
oletrucks is devoted to Chevy and GM trucks built between 1941 and 1959
