That's pretty interesting. As far as the console addition is concerned, I'm assuming the M40 shifter is the automatic transmission.
I think I tried doing research on this previously and kind of gave up because I couldn't find a definitive answer on what to use in a COPO. In Jerry M's book on p. 167, there's a photo of a COPO 427 front coil spring with a "HQ" ID tag on the spring. Additionally, he claims on the same page that big blocks all received heavy duty suspension and used either "HQ" (part # 3955724) or "HW" (part # 3955728) front coil springs.
Now, I look at the 1969 Camaro Spring chart and neither the ID codes NOR the part numbers are listed as options. Hence, I still believe my original question is open, despite my research on the subject.
Jerry, maybe you can chime in here?
If it helps someone give me an answer, my car will be a plane-Jane '69 with power steering, front disc & rear drum brakes, no A/C, AM radio, console, M-22, MQ code 427, cowl induction hood. Think that's about all you'll need.
