I think aluminum rims would have been a lot cooler but the centers do look nice.
I'd probably use any part from the Fujumi or HRM kits that are direct replacements as the castings are cleaner.
I'm not sure which engine to use, MPC MKIV or Monogram Cobra 427 or something else.
Here are the rest of the photoetch parts that were in the bag.
Also be careful as there are a lot of really tiny metal parts in the same bag with much larger resin pieces.
