Thanks for the 'analysis'...we have nothing else to go on with these 1968 Z24's. Wonder if buyers were even looking for SS427's when they went to the showroom...or did they order them? I bought my '68 as a used car in October 1968, with 2600 odometer miles. Cost me $2850 plus $25 for the 50,000-mile warranty. I thought at the time that I would have liked a Custom coupe; but I'm glad that it is a Sport coupe...to me, the 67-68 fast backs have the best styling.
Attached is a side view of my ride.
