Per the VIN # it is a 67 Satellite 383 2-bbl car.
One bumper has bumper guards and the other does not. Which is correct you can't tell without the build sheet. The taillights and bezels are Belvedere pieces, not Satellite. The car was built without the clock option, it does have the fender mounted turnsingal indicators h7 on a fender tag. More than likely a AM radio, R1. The 4-speed shifter is incorrect for a 67. What the seat is out of I can't say but it is wrong. The GTX gas cap is wrong, but a lot easier to source than an original. Ofcourse the steering wheel is aftermarket. All in all it looks like a solid body and is very restoreable. I hope you have all the Satellite side and wheel well trim, because that makes the Satellite IMO. You need to check for original spot welds on the 4-speed hump to verify that it's a true 4-speed. Not everyone is looking for a total correct restoration so most of my input is going in that direction. There is no way in 67 to verify that the engine is original, but you can look at the cast date on the block too verify a late 66 or 67 block. The rearend chunk will more than likely be a 742 casting or possibly a 741, but I think the 383 cars got the 742. The transmission will have some numbers and that can be looked up also. The appearance of the engine indicates recent freshening, hopefully not just paint. If you have any specific questions just PM me and we can talk.
I love the 67's so what you have appeals to me and I will help you as I can.
