i bought mine off ebay they were listed as 12 bolt brackets fit fine. iwasen't impressed with the spacers, they wern't cut squre but did give the right spacing. next one i do i will just use front brackets and weld them where they need to be.aftermarket bracketsonly suport the calipers on the thickness of the bracket unlike the gm ones. we set up a ford 9" with caddy calipers and cut the store bought brackets to use as templates for front brackets and spring perches it was a much nicer set up and easy to do
