1969 Half-Shaft

[Chris Shamaly]

I own a 1969 small block convertible. The rear-end half-shafts on my car appear to have a larger diameter than what I see on other cars. Is it possible that these are aftermarket replacements? Do the half-shafts have factory codes? If so, where?

ALL 1963-74 Corvettes used half shafts of 2-1/2" tube diameter. In 1975, GM changed the size of the PRODUCTION half shafts to 3" tube diameter. Very shortly thereafter the 63-74 2-1/2" halfshafts were discontinued and, these 3" half shafts, GM #360912, became the SERVICE half shaft catalogued by GM for all 63-74 models. They're still available to this very day. Apparently, at some time your half-shafts were replaced with new GM half shafts or used half shafts off of a 75-79 model.

I believe that the 360912 half shafts are manufactured by Spicer. So, they may be available from aftermarket sources, too.

That answers my question. I'm restoring the car to original, so I think I will look around for correct shafts. Thanks Joe.
