hydroboost components query

Following the proud tradition of beginning one project and then embarking on a subsequent multitude of projects, I have bought an 8 3/4" rear end to replace my 7 1/4" stock unit. My plan is to have the thing rebuilt and powder coated.

But then I thought, why not convert over to rear discs at the same time? You know, for kicks. I already have front discs. Let's round out the picture here.

But then I thought, if I'm going to change to four wheel disc brakes, why not top a cherry on this sundae and ditch the vacuum booster and go with hydroboost? I love hydroboost.

But I don't love the idea of spending $1000 on a kit.

I've seen others whisper here and there on various Mopar forums about their own hydroboost conversions, but nothing concrete. My plan is to start with a hydroboost unit from Napa ($150):

I already have the two-bolt later-model Dodge pickup master cylinder. So it looks as if what I would need is an adapter plate for the firewall, some hoses and fittings, and a magic push rod. The hoses and fittings can be done locally by a hydraulic service outfit. That leaves the adapter and the rod. I can't fab an adapter myself and I'm not at all sure what to do about the push rod.

Any suggestions?
