Is it Don Hartmann? (of A Little Different fame- is he even still alive??) If so, he's always been a straight shooter with me. He had a lot of the hood trim and hands down the best repro
H/O decal kit I've ever seen. He was selling
H/O parts like this about 15 years ago. That's the only person I know that may have some of these scoops. If his initials are R.M. from the midwest.... ummmmmm…...
As far as original nos cars and concepts hood scoops, who cares? It's a non-moveable part that doesn't wear out and as long as it's not cracked, has missing or broken mounting studs, or dropped or smashed with a hammer, you can use a used one, as long as you can verify it's an original part. They're pretty hefty and durable- heavier than they look. If you want, I have a spare scoop I can take pics of underneath because that's what counts. Make sure they're sending you pics of the underside, too.
84 cars also used a black decal in the rear section to simulate an open scoop. Most people just paint them. Of course, knowing me I might have one, I just checked- I do have one of those decals somewhere....
As far as payment, perhaps this person has gotten burned from previous unscrupulous buyers who buy a part, get it, complain that they got a broken part, send back broken part to seller and paypal or credit card companies MAKE him refund the a-sshat buyer, and made to eat the cost and he loses a good part in the process. With a check, he has total control of refunds. I prefer money orders so I know the money should be good. But if you want the part, you pay the person the way they want to be paid or you won't get said part.
