If you are sticking with 8 on 6.5 wheel pattern:
The Dynatrac caliper bracket is of nearly no use to you. it is only good for the small 5/6 lug rotor the 8 lug rotors are a bigger od, and that bracket won't allow clearance for the caliper "pins" to clear the rotor.
What you can do, (I did) is use the 60 caliper bracket where it goes over the spindle, and graft it to a Chevy 1/2 ton bracket to hold the smaller caliper, spaced exactly where you want it. i.e. only use the bolt pattern from the 1ton and only use the caliper retaining area from the 1/2 ton. custom built in your garage!
You might want to check with JB's 4x4. He did my axles and he is making a bracket that will bolt to a 60 and allow you to use 78' Chevy 3/4 ton brake calipers and rotors. I clear 15" wheels.
On a Ford 60 front all the Dana 44 stuff from a Ford will bolt onto the Ford 60.
If you are going to a 5 or 6 lug bolt pattern:
You will have to machine your wheel hubs outside to 4.200 or whatever your i.d. of your wheels are and the backside of your hubs for the i.d. of your rotors, then re-drill the bolt pattern of the hub.
