I tried the search function for this and came up empty handed. I'm sorry if this has been covered before. Thank you guys. | | | | | Joined: Jan 2002 Posts: 2,254 'Bolter | | 'Bolter Joined: Jan 2002 Posts: 2,254 | I did this switch to get rid of the cable system that did not work.
You can do it

I'll post outer side-to-side measurements of the metal base for a 54 if someone posts measurements for pre-50 metal seat base. In 1950, the seat was also "made more durable by adding turns to the coil springs and by increasing the gauge of the spring wire"( LCVA article). | | | | | Joined: Jan 2002 Posts: 2,254 'Bolter | | 'Bolter Joined: Jan 2002 Posts: 2,254 | I put a seat out of a 50 3100 in my 48 3100. It fits fine.

I just now looked at a lot of you really old posts, Denny. Many of your old posts are now blank. This problem with the new Stovebolt.com server/software is really a seriously bad problem.
If you width is for a pre-1950, and no one posts a width for a post-50 seat-base, I'll unpack my hibernating 54 and measure the width.
On what part of the base did you span your measuring tape (if that makes a distance). Side-to-side seat base - measured at the rearward side, middle side, forward side.
I do not know if this makes a difference on a regular cab. It makes a difference on my GMC COE seat base, which is different from a Chevrolet standard cab seat base (the COE is the only base I can get to now).

Since they're only talking an 1 1/4" on each side it well might have just been in the uppre cushion band that they widened it. I don't think the earlier cabs are actually 2 1/2" wider. I'm not in a position to start trearing either on of my truck apart right now to take measurements so maybe some one that has their's in process or in a heated garage can follow up.

This is the adjustment for the front to back for leg room. I bought the entire seat which included the adjusters, seat frame, and cushions from a 50 3100. I had to remove all the cable adjustments, frame and cushions for the replacement.
I do not remember any width difference. It seems to me the frame and cushion widths were the same

Works pretty well. | | | | | Joined: Jan 2002 Posts: 2,254 'Bolter | | 'Bolter Joined: Jan 2002 Posts: 2,254 | I wish that I could have done that. It would have been nice
