I'm assuming that the stamped number are Vin numbers? Can someone advise?

And the pinkish red numbers on the top of the tranny, anyone else have these or know what they are or mean?

CB1134583 looks like a partial VIN:

C = 2wd
B = 1981 model year (A= 1980, B=81, C=82, etc)
1 = Oshawa Assembly plant code
134583 = sequential portion of VIN - Chevy nameplate

14030811 looks like a GM part number; 3260 might be a supplier unit number or lot information.

I don't recognize the "219" on top of the case, or can't see enough to get some context. Normally that would be the "broadcast code" corresponding to the 8 digit part number (you can see the "DN" or "DH" in Gregski's photos) or the chassis build sequence number (which would be hand written).
