I used Paul's Chrome in PA. Check out their website. They are very expensive, and make no qualms about it, but they also are very thorough and give you a very detailed itemized quote with pictures. Quality is top notch. I used them for any pot metal rechroming I needed. If you need simpler parts not made of pot metal rechromed, there are probably more affordable alternatives. Just remember that cut rate places might ruin a pot metal part if they don't know what they are doing, and when you dealing with Cougar parts, that's a big problem!
