L78 CRD build code question

[YENKO DEUCE REGISTRY]

Nice car!

You are fortunate that you have a '69 Nova because that is the only year for the 3rd gen's that have the engine code on the Body Broadcast Sheet (what you have is technically not a 'build sheet'). I've heard from some that the 'CRD' denotes that SS option in that it required specific body piercings (SS tailpanel, etc...), but that has not been confirmed. BTW, the M20 notation is actually an indicator that the car is a 4speed as opposed to it actually having an M20 version - it could have an M21 or and M22 for example. The other options are easy to decipher.

The trim tag is pretty plain, just the 732 interior (black custom bench) and the Cortez Silver top/bottom, being built in the 4th week of December with 'A' on the bottom row indicating that interior painted items are black. No single digit number after the 'A' indicates that the car did not receive any exterior moldings, (drip rail, door frame, body side or rocker).

Looks to have the original exhaust on it - and an interesting array of bolt-on's: traction bars with rear sway bar, drive shaft hoop, brake booster removed, pan between the grill and core support, maybe some aluminum brake drums on the rear?? and perhaps a respray (with extra metallic?).

I'd like to hear more about the 427 story.....
