My '71 ain't a '71...or is it?

You guys all missed the mark. Your shooting in the dark with a shotgun. The last 6 digits of the dash vin are supposed to match the 6 digits stamped in the trunk drip rail, and on the radiator top support. Usually an antifreeze sticker covers these on the radiator support. Also those last 6 numbers in your dash vin need to match the last 6 digits in the data plate on the fender. They started stamping in the sequence numbers (last 6 ) in 1969 His dash vin does not match the trunk drip rail sequence number. The dash vin and body are from 2 different cars.
