Much thanks I gave the wrong measurement for that axle! What I've been able to find out, they only made that axle for that truck _in_ 1972 and that makes it dang near impossible to find a replacement. Wife was up 'til midnite last nite hunting, and came up goose-egg. But the wife took me to a yard I didn't even know exist and we bought a -- I think it's a '78 -- axle. With minor mods it will fit under the C-30, and parts ets for it are find-able.
