Keep in mind that none of the trim on Monza's were ever chrome plated. They can be chromed but chroming is not cheap today due to stringent EPA regulations put on chrome platers. Most of the trim is anodized aluminum which can be stripped and refinished. The sill plates are bare aluminum. I have done a fair amount of refininishing of aluminum and you can achieve excellent results. You also have the option of having the parts reanodized (Bright Dip) or just keep the parts polished. Here's a couple places that are known for their quality but be prepared to pay.
