Yes the trans tag looks like the repro ones on the Zip Corvette site, except for the number itself, of course.
The DC rear is a a non-posi 12-Bolt not a Dana, of course. I believe it is original to car as I am the 4th owner and I have spoken to the 2nd and 3rd owners. Original owner was an elderly court judge, not likely to have swapped the rear unless it failed. Also the body build date is 5th week Nov 1966 and the axle build date is Oct 6th, which is consistant with an original rear.
Axle reads DC 10 06G
This is a very original vehicle that has not been "bubba-ized" and has sat much of its life. Parts I have examined so far are all correct and correctly date coded except for replacement alternator, voltage regulator, carburator, and AC compressor.
TAR6569, would you mind explaining where you get the "67 Chevrolet M20 with standard 3:31 axle ratio" information for the trans tag number?
I will post a picture of the tag and the axle markings. The VIN is extremely hard to see with the vehicle assembled and almost impossible to photograph. It is on the top of the trans, in two places, on the case and on the spacer plate between the case and the tail housing, on the left side of the trans. Or possibly on the spacer plate and the edge of the tailhousing, it is hard to tell, but it is stamped with the partial VIN twice. I could only see it by using a small mirror and a flashlight.
Thanks for your input.
