I have two threaded backing plates from my 69 convertible that I don't know where they go. They are about 1/4" thick. The holes are threaded and there is 'H41' stamped on one of the pieces. Any ideas? Thanks.

I just found a home for these parts. They are backing plates for a convertible 'B' pillar to rear wheelhouse brace. Thanks and sorry if I had anybody chasing this.

Glad you found it!
