[YENKO DEUCE REGISTRY]

Not so fast there sixtiesmuscle!

I have collected the drivetrain component dates from many of the '70 Yenko Novas that were produced in 06B. All of these cars except one has at least one drivetrain component that is dated later than the build date of the car. It is usually the rear, sometimes the engine (or both), but never the transmission. (This is true of the non-06B cars as well, the trans is consistently dated earlier than the engine or rear).

I believe that the trim tag has the 'scheduled' build date, so I don't know if they were behind schedule or if they ran out of rears. The '70 COPO Novas have a unique code, 'CBW', and there were only two non-Yenko COPO Novas that went to Canada so we know that these owners did not swap rears with other COPO cars.

I would propose that what we see on 30 year old protecto plates and original rears are reliable proof that some drivetrain components can be dated later than the car's build date - especially June!
