[nickeynova]

some of u might remember my post (do i have a nickey nova) first off i found the paper that was lost. just recently i found a second one in the rear seat back. the first one was on the bottem. the top of the paper basicaly breaks down the vin. n some of the trim tag. my question on the third line down it says, copo-f & so below is a code: zj1 what dose that mean? i don't have a way to post a pic of them. if any one local knows any thing i could show u. thanks
