Sixpac some one did and I think it was on a Dana, I am loooking for the thread but cant find it. it was using a jeep disc and I think a next generation Caliper, Not sure but I will find it it was a very short post to the thread. If any one else finds it please add to this so we can make a contact.

DoctorDiff has a good rear disc kit. It keeps the tapered roller bearings and it installs easily.

The problem with this is that its big old heavy parts,
I'll stick with my light weight Wilwood set up, it
uses 1/4 thick vented rotors and light calipers

I also did the Speedway brackets, GM Metric calipers and Grand Cherokee rotors. My rotors are from a 2000 front. I agree they are kind of on the heavy side, but they are cheap and you can buy everything except the brackets at the local part store.

i agree they might be a tad heavier than the wildwood, but much cheaper, i did the same thing but i used dakota rotors i think. had to have a big hole in the center for strange axles. got 150.00 in all of it, with braided lines. works great and is still alot less wieght than the drums, backing plates ..ect.........

A tad heavier? LOL, they're a lot heavier, and not much lighter than drums. The drums also stop as good and maybe better, so without the weight savings what's the point?

Ok guys we have lost the train for the original poster, He can go onto www.Speedwaymotors.com and look for all the parts, I found 11 3/4 rotors with 5 on 4.5 bolt circle (Mopar Style) the Gm Midsize standard calipers, 2 mounting flanges for just under 200bucks, he will have to do some re-configuring of his break lines etc and maybe buy the mounting hardware for the calipers, that will put him at about 225 bucks. thats alot cheaper than 550bucks when he is tring to pinch and save some cash. I am going to order my parts tomorrow but I think I am going to pull the trigger on a bolt on kit for 299 bucks from Speedway. THis is another great post on this sight
