1929 roadster seat frame
I would love to have a touch more leg room in my 29 roadster. Is it a big project to move the seat frame and riser back a couple of inches? I see machine screws around the base of the seat frame, is that all that is holding it in place, or is it spot welded also? I am sure that thus has been done before I just want to do it as simply and non invasively as possible. Thanks Rich

Re: 1929 roadster seat frame
Deuce man , I made more room in my 29 roadster by cutting 2 inches or so out of the seat riser. I also removed the back shelf tray. I am using original seatsprings and covers with no modifications. That gave me more room then my 32 roadster

Re: 1929 roadster seat frame
Ii need the riser to support the backrest there is no shelf behind the backrest If I could just move the whole assembly back it would straighten up the backrest and move the bottom cushion back to where I want it. I just dont want to butcher up the original parts that have been there for almost 92 years they are very nice. I am hoping for a modification that looks like the factory did it. Certainly someone must have done this on their roadster that can give me some pointers. Thanks Rich

Re: 1929 roadster seat frame
The riser is part of the floor and the seat structure. The way those items are tied into the B-pillar support structure does complicate things. Each item in contact with those structures will also be affected.
I would suggest a custom fabricated seat. The spring boxes are tall on the bottom and thick on the back. A custom made back frame utilizing zig-zag springs would reduce the thickness by a lot when several inches makes a big difference. The bottom can be formed with foam only if a person wants to reduce the vertical profile. With the roadster & phaeton open cars having the lowest belt rail height, seating for big and tall folks has always been a bit problematic compared to the coupes & cabriolets which have the high belt line. |

Re: 1929 roadster seat frame
I am using the top seatriser and just lowered the bottom seat riser and misspoke on the package tray. I replaced the wood backseat for the seat top with a rollbar thats moved back. I too have a very old original or type seat covers but doors and panels were just panel board
