Re-drilling brake rotor bolt pattern? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Thought I'd ask in here as all the project savy peeps use this forum and its not year specific

I've read how to swap NBS rear disk brakes onto the oem axle for OBS trucks. Works great for 4wd's as they are already 6 bolt wheels like all NBS trucks. I have a 2wd, with the 5x5 bolt pattern. Can a 6x5.5 bolt pattern rotor be drilled with the 5x5 bolt pattern so I can put rear disks on my truck? Without the machining of the rotors my disk swap will only run about $400, huge saving vs aftermarket options.
