Okay, I now understand the shift numbers. I'm glad to see that I got the month and day info correct, but is it safe to assume the C designates a Nova? Or is the C the year?

It turns out that the housing may not be all that exciting, The "C" is what I was hoping was different.

I am still slighly suspicious of this pakage due to the GM 4.33:1 gears which are dated 3-70. If the housing was made in 1970 rather than 1969, it leaved the posibility that it came this way from the factory (I think)

My local GM dealer check the avaiability of the part number (actually called Detroit) of the ring and pinion and it came up that discontinued!

I understand that what I am asking is not intended for a true #'s Supercar and only a clone. Therefore I do not want to wear out my welcome, but I still am intereted in hearing if anyone has ever heard of GM producing a 4.33:1 gear, and if so was it ever factory installed? I know they made one because I'm holding it in my hand, and the part number checked out.
