A couple of comments:
1) The 6 lug kits are designed using later model square body caliper and rotor hats for 16" wheels. If you are using 15" wheels, you need to make sure they are designed for disc brakes (yes there are differences) and clear the calipers. There may also be a need for a thicker wheel spacer.
2) That bracket you are working on, note in the kits there is an offset in the bracket which offsets the caliper mounting further inboard a little. Again for wheel clearance.
3) The 5 lug kits have early 70's Camaro components which work with the 15" wheels better.
