Chevrolet 1533X2 30-cwt trucks

[Colin Alford]

That exhausts the information available in the Major Assemblies book.

My read on this information (and the information/study presented above by others) is that “Major Assembly-wise” 1533X2 was essentially the same as 1543X2, but there were definite differences in wheel-base (and therefore frame), cab style, and cargo box.

My inference is that Parts list CC60L-01, and Driver’s Handbook CC60L-HB1 (which both cover 1543X2), are probably reasonable reference materials for mechanical systems in 1533X2 in the absence of the correct manuals.
