drum to KH 4 piston question

does any company make a rotor w/ 5x4.5 that will direct replace a original k h rotor w/ 5x4. I want to go to bigger bolt pattern to increase my choice of wheels but I don't really wanna go through the trouble of replacing the disc brake system. Also has anyone ever had 8 3/4 axles modified to a bigger bolt pattern?


Direct NO but modified by your machinist yes.
It is possible to get a BBP on your Kelsey Hayes SBP set up. It takes some machining and here is the details below as posted by Longgone.
