SBP Disc Conversion

[74Dusted]

1971 Dodge Demon, Supercharged 426 Hemi "Street Car" project

I'm finishing up my frame at the moment and pondering my brake system while i work. I'd like to keep my 5 on 4 (SBP) Wheels & Brakes when i convert to 4-Wheel Power Discs. The car currently has 4-Wheel Drums.

I'm going with a SBP Rear Disc conversion, using slightly modified Shelby Daytona Rotors, and possibly Grand Cherokee Calipers, if not it'll be Shelby Daytona Calipers & altered backing plates for the Drum in Rotor E-Brake setup. I'm still working the kinks out of that plan, and it changes a bit as i research other parts.

For the front of the car, i've got the Stock Drum Brakes (9" if i remember correctly), but i'm swapping the '71 K-Frame and everything on it for a 1973 "340" Disc Brake K-Frame (with Draglink, Power Steering Box, Spindles and everything else. 340/727 is still hanging on it too). But it's Large Bolt Pattern. I also have a set of Kelsey Hayes 4-Piston "340" Calipers on the shelf that i was planning to use on the '71 Demon with the SBP Brakes.

So what are my options/what can i do to convert to SBP Discs and use my 4-piston calipers too? I also have a '71 Duster with 10" Drum Brakes (eventually getting LBP 4-Wheel Discs and a Supercharged R3 Engine) if anything from it could be of use in the current project

Kelsey Hayes 4-Piston calipers aren't compatible with anything you have. It would be tons of work to engineer something when you could just buy the correct parts.
