Hi! I have a 60 corvette made in Nov. 59 with strange stampings on the rear axel. Casting no. 3725899 Casting date. C 38 Axle code & date stamping. BA 13 (that is a little hard to read but I am quite sure that I read it right) I would guess that it is not original but if not what kind of a axel is that? I also checkd some other items when I was under the car to see what I found. I could not find any no that seemed to be for my car. They are: Bell Housing (right side) GM 3840383 Gear box (Righ side) GM6 / K / 338835 / C13 (left side on lid) GM 8281888 Gearbox tail (right side) 8261884 (left side) 1~28 I would be very happy if you could help me out to sort some of this items out, specialy the rear axle. Best Regards / Niklas
