Yeah, those rims are for the 30th Anniversary Trans Am'* Only. There were 500 American Spec Convertables and somthing like 2000 American Spec Coupes. Regarding the 3M Compound: The Perfect It II is an abrasive compound that I have found works really well to help blend the paint and work out large swirl marks. Then if you follow this up with a nice polish, those swirls made by the actual compound will be worked out leaving you with a perfect, swirl free finish. I have found that 3M makes pretty good products. There is another brand that I can't think of that a lot of people use too, but I can not think of the name. I'll get back to you on that one. Basically, my reason for being specific with the 3M, is that from my personal experience, I have found nothing to work better. The 3M with my PorterCable gave me reasonably good results. I will also post up with a good site of how too'* if interested.
EDIT: I am not sure on the 30th Ann. Coupe Numbers. It could be 2500.
