North Racecars SN-95Cobra 11.65 kit for Fox body length axles.
Bought the caliper brackets, hardware, Fox length 5-lug axles(Yukon 28 spline), and the cables for $440, they don't list that as an option, but if you call and talk to Richard - that's the deal.
Traded in a set of junkyard core calipers (SN-95)at Advance Auto and a $100 for a pair of reman calipers, and another $25 for cheap pads until my Hawks get here.
Bought a set of new brake lines from Classic Tube, already modified for the brake conversion for $40(in Stainless Steel). With these tubes, this was an absolute plug and play modification.
Here's the part number....

Took about two hours to install everything except for the parking brake cables, everything fit good. As I'm changing around the parking brake lever/mechanism, I haven't assembled the new equalizer, etc. yet.
