Ah, this topic again. It's been discussed some before.
It's in the definition of COPO. If a COPO # wasn't generated, then it's not. Lots of paint approvals and lots of fleet cars went thru the Central Office. They are special orders that required some type of review/approval (and some say ordered via a COPO process). But special order does not equal COPO.
A COPO required engineering work and a COPO # to detail the changes. Most were trucks (changes in wheelbase, mounts, etc), some police cars, and a few hi-po's....
