I like the 66 Valiant conv. The 69 swinger looks to be a clone. That would have been my first pick. But all 340 cars came with drip edge trim. That car has the delete corner which is always a dead give away it was a /6 car
My friend knows the owner and car, said at the show it’s a real 340 car but had a big block in it now...I had no reason to doubt him so I never looked at the VIN.
