Greetings,
   I have looked high and low to find more details about this Jegs GM rear disc conversion kit. I even emailed Jeg's with zero help other then they say it will not fit.

It is by far the cheapest and looks complete rear conversion system out there. I just do not see why it would not fit.
I wondered if the caliper mounting brackets would be the wrong bolt pattern size or something.  Looking at my truck and the kit I do not see why it would not fit.
Has anyone bought this kit before and installed it?
I am almost tempted to buy the kit and even if it does not work, simply by the brackets from Captain and use it.

Thanks, I am new to the forum. I have had a mess of square bodys and really like them. Love this forum, just shame it took me forever to find it....

UGH...why does this happen once I ask for help, I am able to find my own answer...Add that to Murphy's law.

 "The included rotors are 11.14" with 2.786" hub I.D. and holes for 5 x 4.5" BP utilizing 1/2" studs and 5 x 4.75" BP utilizing 7/16" studs."

So the rotors are the wrong bolt pattern.....

Also, depending on your truck, the Jegs setup will not work with staggered shocks.
The shock interferes with the caliper on the trailing side of the axle housing.
