after an shitload of digging into it…. I finally ID’d the interior of the 56. Split bench is out of a 67 Impala, steering wheels is early 60s Pontiac, doors and rear wall skirt are custom stitched and the arm rests looks ot be from a mid 70s Boeing 707. Did I mention the Kraco (yep, that’s right, Kraco) AM/FM cassette deck. If I can get it to work, I can rock my mix tapes from 1988. Sweet!
