1969 k5 rear disc question

[BigObOoGiEmAn]

I just want to start off by thanking everyone in this forum it has been a huge help to me and a giant wealth of information. I don't think I have posted on the sight before but I do use the search option often. I currently am working on my 69 blazer. I just picked up and eaton 3 series posi for my rig pretty cheap and is a huge improvement over my current one legger. I really want to swap to rear disc during this install, but am finding it pretty difficult to find the correct caliper brackets for what I want to do. There seems to be a lot of options out there for the c10 pick ups but most don't run 6 lug and for a lot of guys out there they want to still run 15 inch wheels. I have seen a few post of people running 99 and up 1/2 ton disc and Camaro calipers which seems to be a very nice option being that they are 13 inch rotors and very cheap to acquire. I really am not concerned with parking brakes or any of that either. Does anyone have a line on where I can purchase mounting brackets of any kind bolt on or weld on? CaptainFab on here made them at one time but after contacting him they are no longer available. I also want to note that I did use the search function before posting on here so try not to rip on me to bad.
