Ordered My Disc Brake Conversion Kit

The price is about the same as a 73+ disk conversion from Dr Diff. Which makes sense, because it's literally just a 73+ disk kit with a different bolt pattern drilled on the rotors, unless maybe they're turning the hub diameter down too.

The booster cost is the biggest price difference, but that's because Pirate Jack is selling a generic $75 booster where Dr. diff is selling a fairly accurate Bendix style reproduction of the original.

But I am looking forward to seeing what they're doing with the rotors, that will be the biggest consideration for most folks. If you can't keep the OE wheels because of the hub diameter you might as well just use the standard version of the 73+ disks and go BBP.
