I have worked on two 69 COPO Camaro's, one had a front spring "YP" tag and the other a "HH" tag.
Any others you guys know of that were actually used ? Mike |

Am curious Mike, wouldn't the L78s weigh nearly the same as a COPO and therefore have the same springs up front?

HQ was used on the first two ZL-1 Camaros.
Spring selection was based on weight. A car with many options may use different springs than a low option car.
