C1 Rear Axle Casting #

[Christopher L.]

The casting number on my 1958 rear axle doesn't match the database I have in my library (very limited). The casting number is: 3707306 GM10. Is this casting number correct?

GM #3707306 is the casting number used for 1956 passenger cars and Corvettes. This is a housing used for non-positraction since 1956 did not have positraction. It is generally functionally interchangeable with the 1958 housing but it's, of course, not correct.
