Well, I have successfully found every V8 ZQ8 VIN between Chevrolet and GMC across both the United States and Canada. In total 1109 V8 ZQ8 trucks were built. I have 140 VINs left that I still need to pull the build data on. Once I complete that, I will add them to the 3LT database so all V8 ZQ8 Owners can puruse every trucks build data by sequence number. No VINs will be in the public database that I publish later. This is to protect owner's and their trucks. It's been a long 5 years of seeking and validating, but I am finally going to finish what I originally set out to do. In the coming weeks, I will edit the original post on this thread with updated production numbers between both brands and segregating between USA and Canada.
So happy to finally be in this position!
