Chevy only offered the 116" WB in 1/2 ton trucks, and only 125 1/4" in 3/4 tons.

The FAM (figures dated Jan 1954) indicates that the frame width for 1/2 tons was 46" (outside measurement) and 3/4 ton and larger trucks it was 36".

Here's the Vehicle Info Kit for '54.

If you're smart enough to take it apart, you darn well better be smart enough to put it back together.
