I will take some shots of interior tomorrow in the sunlight. I know the interior is not original but it is old style look. The door panels on the 52 should have curve, but doing it myself, easier to keep stitches straight.
I made 4 inch seat extenders. I am 6'10" and it gives me more leg room but puts seat back 1 inch from rear seat. I either put seat up when I have people in backseat or they need to be a double amputee.
I added seat belts because I lost a friend that died in a accident in a 1949 Chevy back in 1989, I always install seat belts in all my cars.
(typo at beginning post, steering wheel is in final stage of Clear Coating, temporarily using 51 kaiser spare steering wheel)
Here is photos of one of the door panels.
