I have decided to tear out and re-upholster the seats on my 1939 Ford Panel Delivery. The seats are the original, yet they're in pretty bad shape upholstery-wise. I removed the passenger seat and all its upholstery, and have removed most of the burlap/horsehair padding.

Prior the getting the seats sandblasted, I assume I will need to disassemble the seat back from the seat bottom. However, the bolt that holds it them together is puzzling . I am not sure how to remove it. The seatback pivots on this bolt, yet neither the outer dome bolt, the inner washer, or the inner bolt move. I would assume this setup is common to Fords of this period. Can anyone tell me how to remove them? Should they just slide out, or what? Thank You.

In the first picture it looks like it's just there for a hinge point to me. If it's a shoulder type bolt it may be made for the nut and washer to tighten to the shoulder of the bolt itself,, I'd put a wrench on it and see what happens (or leave it and paint away!)
