Keystone Klassics

Do any of you fine folks hiding out there know of any place that refurbs these rims? My bro has had these forever on his 68 Dart and likes the look (me too). But... they need help, old age ya know! Any info would be appreciated. Thx all
The problem is the process. The wheels are aluminum and steel. I was told there is a problem with removing the old chime from the alloy mixed wheels. Good luck on your search.
