I went and looked a 4 trucks on Saturday and a couple I think it said s112 and the other one was a r100 on the side of the cowl and the one I was most wanted just had 100 on the side they are from 1950 to 1956 he thought the one I was most wanted he thought it was a 1953 but it is all tore apart it is a short box truck
L Series is 1950-1952, R series is 1953-1955 and the S series is Late 1955-early 1957. Early R series and all L series us the same cab with the 2 rear windows and small door windows, 1950 only has hidden hinges where all 1951-early 1957 have exposed door hinges, Late R series and all S series use the same cab with the one rear window and larger door gl***. The 100 series are the light duty shortbed pick ups, the 112 is the 1/2 ton with extra leaves in the spring packs. Most parts are swapable between all L-R-S's.
Terraizer...thanks....now if I can remember it...looking at a 1956 that has the wrong hood ? or so the owner's been told....
