Re: X66 COPO's
 

So did the X66 Yenko's have the curved neck radiator, blacked out tailpan, did they have SS embplems or were the emblems deleted with the COPO designation, and were they ordered as double copo's as well? If they had a factory tach would it have been a 7k with 6k redline?

X66 Yenkos did indeed have a curved neck rad, black tail panel, as well as black rockers and 1/4 panel louver trim... but no SS emblems. (they were factory shipped with the base model style blue bowtie grill and tailpanel emblems, with a plain Camaro script on each fender) The X66 Yenko cars also had the complete 9737 package, but the factory tachs were not ordered in this first batch...aside from the 140 mph speedometer, they had no optional factory instrumentation, but SW tachs(and sometimes additional gauges) were added at the dealership.
