Road Runner Nest

I have been calling around for years now.
And I have found a lot or refurbished,nos or new molded fiberglass
parts for roadrunners,satellittes and gtx's

However the one part assembly that is very hard to find complete new,used, nos or otherwise in servicable condition
is the 1972 roadrunner,gtx grille and bezel assembly.

I was wondering since I have asked suppliers if they custom fabricate this and the answer is no.
Does anyone know of a supplier that manufactures, reconditions or deals with this part assembly directly?

The sad, but true answer is, none that I know of. That's why good condition originals fetch $500 or more.

I wonder what the cost would be to setup to reproduce them? I'm sure there would be a market for them, not a huge one, but it would exist never the less.
