not a 9" but D35's, D44's, D60 and 4 bolts.

Should be able to find a rotor with the right lug pattern that will fit on,
Find a caliper that fit that rotor with ease. I prefer Chevy stuff as it's
easy to get, cheap and the way it mounts make it simple.
Then either build or buy a bolt on, or weld on caliper bracket.
Assemble and plumb

Yup, I've done it about 3 times. Chevy 1/2 ton calipers, Ford 1/2 ton front rotors and brackets from Stock Car products.The rotor mounts on the inside of the flange with the rotor facing inward. You can get longer studs from CarQuest. Rough numbers:
Calipers $30 each $60
Rotors $40 each $80
Brackets $20 for the set $20
Studs $2.50 each $25

Approximate total: $185

I used 78 chevey k10 front calipers, 79 ford F-150 rotors, Brackets were bought from www.speedwaymotors.com . I would provide the direct link to the brackets but it seems their site is not working???

Only difference between what I did and Plato2k5 did was he mounted the rotors on the outside of the flange where I mounted mine on the inside. Upside to what he did is that the rotors can come on and off without pulling the axles. Upside to what I did was to get more clearance between the caliper and inside of the wheel. I liked that because it was easier to power wash out the brakes.

If you do a test assembly both ways you will be able to determine which way you like it.

The k10 calipers are very nice. Just two sliding pins to pull and off it comes. There is no E-brake hookup.

I put disc on my 72 Bronco Front & Rear. For the Ford 9" I bought the kit from Jeff's Bronco Graveyard ($295), it bolts on. Took me about 30 minutes a side to change. Need to buy G.M. single piston calipers (get them loaded) and they will have the pads too. If you want the e-brake, buy rear calipers from a 79-85 El Dorado, Riviera, or Tornado. I believe I have about $375 into my 9" axle, but it stops on a dime with 35" tires.

do they tell you what rotors you need though? Sure you can buy kits out there but they require you to buy THEIR rotors.... which cost a good amount of change when they need to be replaced.

I love how mine stops.

I also swaped my master cylinder out and added a prop. valve to adjust the rear line pressure. I can stop when i need to on 35" tires as well :)

Chevy half-ton calipers, Chevy half-ton rotors, weld on brackets.

(running Chevy 6x5.5 bolt pattern on my 9").

Also swapped out master cylinder (manual brakes) and it stops 37's like putting it in reverse
