What is the big difference between a B-57 and a B-67? The 57 only comes in chassis version S where the 67 came in T,LT,S,ST,LSt versions. They both use the same cab. Is it the 57 that only had wedge brakes avaible.I know many B-Models overlapped specs but I do not know any differences maybe the 57 had the fish belly frame. Thanks Joe D.

I think the B53 had had the fish belly frame and the B57 had the single frame with fish plated sides and the cheaper 34 rears on walkin beams with wedge brakes?? B67 was the single axle version and B57 was the tandem axle version. I know that was the main difference in a B42s and B421s. B42 came with camelbacks on 38's standard with a double frame and the B421 you could get camelbacks and 38's or walkin beams with wedge brakes and a single frame fish plated. use to be a B57 around Poland Ny with a 237 or 300 under the hood, on 44's with a roadranger still workin. truck would run 80mph easy.

For comparison, the respective models that replaced the B-57 and B-67 were the DM and U models. The S is for six-wheel, the B-67 was also available as a tandem. L = light weight (aluminum components), T = tractor. The B-57 was a tandem or tri-axle heavy duty straight truck, often used for dump and mixer use like a DM.
