Even I have trouble with this one

[Kurek, Larry]

Bzzzzz....

Wrong. The ZR1 was also an RPO code in 1972, however I do not recall
exactly what its implications were. I recall reading in Corvette Fever a
few years back, where they did a coparo between a "new" and and "old"
ZR1. The only reason I remember this is because I also have a 1972
Vette...
