OK. Not much luck when I posed this question in the GT40 forum...

...so I'll try it here.
I have 1 of 2 projects that I would like to pattern seats similar to that you find in the GT40's: Leather/vinyl with the aluminum/brass/stainless inserts. I'm quite sure that such material won't be found on the shelf and will have to be fabricated using the inserts. The question is...where?

You may want to give ERA a call, I think that they use the seats you are after in their GT40,and they may be able to help you out.
