Hemidenny K member club?

Ok. I am trying to figure out how to get big brakes on the cheap. Cody's setup sounds like the cheapest way. I have the 70's mustang hubs already. I was wondering if there is an adaptor needed for the cobra caliper to bolt to the M2 dropped spindle. The Dr Diff uses an adaptor for the caliper to bolt to the stock mopar spindle.


Also will a 17x8 wheel with 5.72 backspace work on this front end?
