I got a pair on ebay from seller 60to0brakesystems, they are very nice. $419 + 39 shipping and $50 for the correct proportioning valve. The proportioning valve is just like the stock unit and matches stock front disc brakes. That includes the e-brake cables, and ebrake style units. I think if you do your research you can buy them cheaper from a local parts store but then you have to make or order custom brackets. I just bought them to make it easier.I know there are a few places that have a kit for the rear. Just wondering if any one prefers one over the other or what setup you guys have come up with yourself. Thanks!
