Following is the quote you requested:
Pricing is based on show car quality finish. The final price may vary depending on the amount of cleaning, straighting and repair work necessary to prepare the part(s) for chroming. (Unusual pieces, outside of classic car, classic truck or motorcycle parts, may require a phone call to get a closer estimate.)
