Mike - I wouldn't think you'd get anything from Chevy, unless you wanted to get into their 'authorized repro' program and pay the fees

not tellin if they could even come up w/ the engineering specs now, and no there haven't been any repros made yet, and considering the probable lack of demand, I doubt there ever will be
I have run across the panels/burbs at wreckers, and have gotten rare bits like the license holder/light, so the stuff is out there - there's a place in Montana I think it was that currently has 3 TF panels, and I got parts from
one they had here in BattleGround WA a few years ago
