I got mine from a local shop , exchange, for $150. They were MoCo calipers off another 2002 king, so i decided to take a chance with aftermarket chrome. I have used the shop for several small items and they seem reputable. They look great now, time will tell.
Buckethead, If you are comfortable removing and disassembling the calipers, you can be comfortable sending them off to www.chromemasters.com to have them plated. These guys did my fork legs and a few other parts for me. Nice work and a decent turn around. The website says $70 each for the late model calipers. I may send mine off if I lay the bike up this winter.
