I can't seem to find anywhere what these RPO codes mean for my 1994 Camaro 3.4 A4:

C9C - Suggested Black Exterior Paint, however I have Patriot Red Metallic, but my sail panel and side mirrors are black, is this what this means???

R7A - I found that for the 1996 LT4 powered Grand Sport Corvette it is Control Sales Item No. 26, is this the same for us? What is it?

R7R - I found that for the 1996 LT4 powered Grand Sport Corvette it is Control Sales Item No. 42, is this the same for us? What is it?

NA5 ??? Emission System, Federal, Teir 0 ??? was this a different emmission sytem? I have no AIR Pump if that helps...

17P Wheel Color, Silver ??? Is this what It is?

8TC & 9TC I assume these are for my rear springs but I don't know...

Any input would be appreciated...

R7A : CONTROL SALES ITEM #26
just some ordering code
R7R is another

NA5 is the regular Federal emissions package (as opposed to the California pkg.)

8TC and 9TC are the LH and RH rear spring codes.
