Need Help! 3/4 Ton rear disk brake conversion

I've been searching here and on other sites about converting my 78 K20's rear drums over to disks and the more I read the more confused I'm getting. I found a bracket kit from Off Road Design but like most of these bracket kits you need to add a drive shaft brake or similar which is something I'd like to avoid. I'm also given to understand that one can use eldorado calipers and maintain their e-brake which sounds good until you realize that these things are expensive in comparison to regular calipers. I'm also understanding that I could swap out my corporate 14 bolt with a newer AAM 10.5 or 11.5 and gain back the e-brake but will have to re-position the spring perches.

So far, am I correct in these assumptions? Have I missed anything? Any suggestions?
