I was at a local car show at a flea market today. I talked with several of the owners and those with 34-36 Fords and Chevys and 48-58 pick-ups were using seats from newer vans. Most were using seats from a Caravan. One had bucket seats from a Caddy. The seat can be adjusted to any height, distance, or tilt with the push of a button. Hope this helps with any ideas you might have.
