things I noticed .......
does your build sheet specify a console? and looking at your buildsheet does "conventional spare" mean the little space saver spare and not a fifth full sized ssp wheel? I also notice on my eminger invoice it specifys "Oregon State" where yours does not however the order date is the exact same (12/22/83). Your build sheet also specifys "Oregon". Both my OSP cars have cruise and gray interior and yours is no cruise with blue. They are actually duplicate cars except for the paint color. Your car is equipped with rear defrost also where neither of mine are. Lastly my eminger invoices include "delete paint stripe". All the inservice pics I have seen of 84 OSP cars show they didn't have a paint stripe.
It sure would be nice if these cars could talk.
It would be easier to figure them all out.
