There were only about 4,889 1969 X22's built. ?
X22 was an internal Fisher Body code used for
part of the model year at Norwood. No Fisher docs exist to verify any of the X codes; over the years their meaning became apparent. X22 is a Camaro SS 396 with Z21 style trim group. RS equipment included Z21 so those also had X22 tags. A few early production COPOs also had X22 tags. Z10s & Z11s w/396 were not X22. The body tag and its information was not used by Chevrolet.
4,889 is the reported production total for Camaro SS with the L78 engine. It has been mis-stated for decades. COPO build records list the L78 engine so it is not accurate. There were 69 ZL1s and 997 L72 COPO Camaros built so the actual L78 total is 3,823.
I don't understand the 1/1 obsession. Some of the most valuable 1st Gen Camaros-COPOs-were ordered in batches. The 50 Gibb ZL1s were built in 5 groups of 10, 6 4-speeds and 4 automatics in Dusk Blue, Fathom Green, Cortez Silver, Le Mans Blue, Hugger Orange. A few years ago a collector paid $650,000 for a silver automatic Gibb ZL1 and I'm sure they knew there are 3 more just like it. Many Yenko Camaros were also ordered in batches; there were 10 Olympic Gold 4-speeds built, all the same.
Shelby Cobras, GT350s, very few of those are 1/1. Doesn't seem to matter. Some of the most valuable cars in the hobby.
