I have this early T10 that I have had for quite a long time. I do not believe I am going to use it so I want to take it to the Nashville AACA meet in a couple weeks to sell. I got it under the impression that it was a '64 Corvette Close-ratio box and that it had been internally gone through. The outside is clean but not perfect because it was meant for a survivor car. Whatever. Dates on the side cover and tail are '62 and '63. Hard to interpret the date on the case. It is an iron case and aluminum tail. It does have a 27 spline output, but according to the charts I find it should have a 3 groove input shaft which it doesn't (only 1). The stamped number on the left side is WG2431. I think it must be a conglomeration of parts, but what is there looks nice inside. Any idea on what it really is? Any idea on worth? I do not have a shifter or yoke for it, but it does seem like it could be put in and run as-is.
