help with ID on old Cutlass

[rollin_on13s]

I'm looking at a 1970 Cutlass in Mesa, Az. The car seems almost completely unmolested except for one repaint with a non-original Teal color over the stock Gold. I've done my share of bodywork, but cannot see that the car has been through a major collision repair.......

But- the car has a 1970 Cutlass rear bumper, and a 1971 cutlass front bumper (with the round turn-signal holes). Both bumpers have all of the lenses, grilles, filler pieces attached. It's weird.

Does this make sense to anyone?

can you post the VIN? I'll try to break it down for you.
