Who made my IROC tail?

I’m about to have this painted and was curious if anyone knows the manufacturer.

I was told it came off a car that was built in the 80s, the fit is very good and I noticed there is a lot of fiberglass weave, as opposed to what I call chopper gun construction. It also has an interesting inner liner that I haven’t seen on any other IROC tails.

No markings or stampings I can find.

Any ideas?

bump...no fiberglass historians?

This is everything you wanted to know about tails

Thank you....nothing there quite like this one so it will remain unidentified aftermarket!

Off to the paint shop...
