I think the most important thing right now is posting ways to find these things out. I have no idea what "horizontal/circular gas-cap finish" looks like, much less "dimples for diffuser bolts to cross member" and I have no idea how to tell if I have a wiring harness for the running lights.
Also, don't all early cars have dual oil coolers? I don't think the sports package has anything to do with that question. I could be wrong though. All in all, this is a great! Thanks for the effort.
