Now I'm confused - I've seen too many pictures, diagrams, swaps, retrofits...
Which way do the stock Kelsey Hayes disc brake calipers mount? Toward the rear of the rotor, or the front? It appears they can be mounted either way...
Towards the front, definitely. I don't think they'll even fit the other way. The four holes in the spindle which position the caliper bracket are not evenly spaced, so you could not mount it backwards AND have the caliper line up with the rotor.
