How do you tell the differance between an original CC-4 and a CC with the standard front axle added to it. I just purchased a 38 CC-4 (I think) and I am wondering how to tell exactly what it is. The serial number plate on the tool box has the letters CC on it. It is on cut down"s with the rear wheels mounted like an early C with the tapered axle and nut instead of the six bolt mounting. Any ideas?
