Hi Ashep65K,
Are the non-metal trim pieces plastic or fiberglass? Originals are plastic with texture, suggesting that the aluminum trim is also original. If the non-metal trim is fiberglass, making them repops, that would suggest the aluminum pieces are re-pop. Both original and repop aluminum trim are, you guessed it, both aluminum. If you wanted to get real serious, you would need to have the materials analyzed for the added alloys. There should be a difference to originals if repop. I'd say all the pieces look original.
