I was looking up the Legend GS Calipers and it looks like Autozone is actually selling the rebuilt ones. They're Duralast branded rebuilt calipers for around $45 if you send them in your core calipers. I have to find out if I can send in a different core such as the wrong calipers I bought or even my 4 cylinder ones. But assuming that I can use a different core caliper, would you guys trust a Duralast rebuilt OEM Legend GS Caliper?
