Just might be a GM part number, but I just checked my Aug '76 parts book and its not listed. It's possible that it's a later part installed as a replacement. Just a calculate guess. Dennis
As Nowhere Man said, it's a casting number for the flange on the ends of a drive or half shaft. It wouldn't be unique to Corvette but would also have been used on many other Chevrolet or GM vehicles.
The 3707778 part number dates it to the mid 1950's originally and most likely truck applications. It was most likely never available in service.

Thanks for that. So you're saying this 1/2 shaft is not necessarily used in a Corvette or it is not used in a Corvette?

The complete shaft assembly like the one that you have is only used in Corvettes. The cast or forged ends that are welded to the tube section would have also been used in many different drive shaft assemblies for different vehicles.

Had this happened to me in past, swore I had the wrong u-joints finally found out that some times you have to get a clamp and just make sure the caps are seated the grease in the caps will prevent you from getting the clips in the grooves after assuring the cups were seated and switching clips back and froth found the right combination & still needed to take a small hammer and punch to assure clips were fully seated in the groove
