KH disc brakes, LBP

I only know that they're tough to find for SBP. LBP must be rare as hen's teeth.

I don't think they exist, just throwing it out there to see if anyone knew something. I think if you used a combination of parts like a Wilwood hat drilled for dual bolt patterns you might pull it off, but I'm not sure of this. Seems like a lost cause. Too bad! They seem like cool parts.

I've also been told the calipers are trouble. Anyone know why?
