1953 Buick Roadmaster Riviera seat adjustment

[Native]

is there a built in adjustment to move the bolt holes back? Some other cars I've had have had the ability to move the seat back on the brackets.

Yes, some other cars have had two mounting positions on the seat, this would allow you to relocate the seat further back or forward accordingly based upon owners legs and belly.

-  No original adjustments were provided on 1953 Buicks for the two-way (forward-backward) powered front-seat location.

-  An original front seat should be able to move a total of 4 1/2 inches on the adjuster. Fisher Body had a recall on seat adjusters and the BPSB's address the issues.

-  No OEM adjustments were provided for the fat-bellied owners. Au contraire, if a previous  owner of your 76R was short and thin and needed the steering column lowered, he might have had the optional spacer installed between the underside of the instrument panel and the top of the steering column to lower the steering column as originally provided on a 1953 76X with the lower windshield. You didn't post any pictures. 

 

 

-  Anything is possible. If you were to move the front-seat adjusters more than 2" toward the back-seat, the hydraulic cylinder's rear mounting bracket would cantilever somewhat when you relocate the bracket because of the floor-pan slope. The captured threaded tube-nuts, underside reinforcement-plates and body-stiffeners for each adjuster would also need to be addressed at the same time. In addition, you should consider the access for a rear-seat driver. Even with the OEM tilt-away front-seat feature on two-door models, it's already a tight squeeze.
