i would suggest you never drill the knuckle.
spindle maybe. and its what i do...
brake anchor no problem.
there was a separate kit at one time to upgrade both the big 5 hole and 6 hole broncos.
the 6 hole small pattern is the one you get from the chevy and redrill its holes or just run the ttb abs spindle and redrill the anchor plate of this kit.
there is a offset issue that needs spacing...so redrill chevy spindle usually best deal.

if i find the right truck at the junkyard, i can do the junkyard setup under 200 bux. that includes buying new calipers, rotors and pads.
