As for the gas tank that was shown and some one "thought" was a outer mounted unit for a 67-72 GM pickup, I would guess it may be a 61-64 Chevy sedan unit. The trunk was very deep, so the tank had to be mounted above the rear axle.

There was a post recently where the OP posted a question about a gas tank pic...
