I hear ya, KB is probably among the more expensive options.
Be sure to invest in a brake flaring/cutting kit, I think I got mine on Amazon real cheap many years ago and I have used it a good number of times. OTC brand, I think. You'll need it for rerouting the one line going to the rear. You'll need a female union, probably M10x1 bubble flare or whatever you prefer to make for the new connection. The factory Y-block on the passenger side will get smashed by the upper control arm if you don't relocate it. So then you'll also need some sort of T-junction to go from one and split it into two for both rear brake calipers. You might also need the 99+ parking brake cables because they are just a bit longer than SRA ones.
To ensure you don't get "Cobra Clunk", don't re-use your OEM forward mounting bolts; instead get the bolts from FTBR. You can either get 14mm or the 9/16" (14.2mm) bolts. Get all delrin bushings because that sounds more your speed. Make sure there's a forward diff brace, either OEM or aftermarket.
You may need to source a custom driveshaft from D&D Performance or somewhere else (really depends on transmission.
Have a big ass pry bar, a flat file, and a sledge hammer. Better yet, those things plus forward torque box spreaders from FTBR.
