VIPER CALIPER BRACKETS

Need 73-76 large bolt drum spindles/knuckles

Right, but those are still an "off the shelf" part. And I already have a set.

What I am worried about is what do you do for a hub and rotor if you buy these brackets? I know Andy isn't making the custom hubs anymore, and I think the rotors were some OEM rotor that needed machining to fit and he also isn't doing those anymore. I also know that Dr. Diff used to sells a similar kit, and his Stage 3 Cobra kit uses a similar hub but (I suspect) a different rotor but no idea if his hub is available separate nor if it would work. In the end, the rotor might not be a big deal (provided the original application is known), but the hub is a bit of a stickier point.

In the end, I am concerned that the missing custom parts will mean that I can't use the brackets. So I am asking for clarification.
