Hy z48, the parts book breaks down the part number a little differently
8 year, in your case 1948, but must confirm by body style
14 is the series code for a 3/4ton or one ton Chevrolet
23 is the model code, it confirms it as a 3/4 ton 125 1/4" wheelbase chassis with cab.
the remainder is the vehicle number, hope that helps.
