So to get the adapters to fit the hubs did you just have to machine the center of the adapters and not the lug holes?

I didn't have to machine the adapters at all. Just the hubs and a little bit of the front rotors. I'll post some pics so you can see where.

Yesterday went pretty well. I finally got the adapters mounted and the truck sitting on all four wheels!! Here are the results. I have no brakes right now so you'll have to settle for a few in the shop pics right now.



Here you can see where I had to have the hub machined to fit the American Force 8 - 10 lug adapters. It's a very small bit of metal that needs removed. I had the same problem with the front but I was able to just remove the lugs and grind it down with my angle grinder. The rotor spun while grinding and gave me a nice consistent spin so I could keep the grinding even all the way around. I don't have any pics of the front yet because I ended up doing it to the wrong set of rotors. The ones I have are 1.5 inches thick and my calipers won't fit on with the pads. So now I'm having a bit of trouble finding the right rotors. Once I do I'll post pics.



These rotors are perfect for a 1 ton rear disk brake upgrade on these trucks! Front rotors from a '77 3/4 chevy 4x4 bolted right on. The lugs press right through where the drum was. Now I just need to fabricate some caliper brackets.

Finally sitting on the ground!



Next step is a 4 link and bag setup. I'd like this thing to sit a little lower yet. Can anyone recommend a good heavy duty 4 link that I can still tow with? I'm gonna notch the frame and build a cross member with a gooseneck attachment. This rig will be the one that tows all my buddies cars to the shows

DIY4X.com and many other sell the rear caliper brackets. They are the same for a 14-bolt or an eaton and can be had for about $40-$60. Use cadillac eldo rear calipers to retain the rear parking brake.

Thanks for the tip, those brackets look sweet! Do the Cadi Eldorado calipers fit over the thick rotors from a 77' 3/4 ton front end? That would be pretty sweet as well!

They should fit without an issue they are almost identicle to the factory k20 front calipers but with the parking brake.
