Rear Brake Caliper Kit DIY

I'm not a big fan of the inner drum parking brake on the 4-runner rears so I think I've come up with a decent kit but will need to fab up some parts. The kits they sell out there are pretty expensive so I'll be doing it myself. I make and sell kits for Harleys and used to make some for VW's in the past.
I'll still be using the stock rotors but I just found a Ford Explorer caliper which will work. For the fabbed parts, I will make a parking cable adapter and caliper hanger hopefully to be installed without having to take the axle shafts out.
