Re: The "General" wrong?
 

In another post here I showed part of a build sheet found in our COPO Chevelle. The vehicle was built 75 before ours. In the documentation that we got from GM in 1988, They listed ZP8 as special trim. and left out ZV6 and ZN1 all together because they had no information on them. I think the guys here have most of these odd ball "Z" codes figured out now.
