360 Magnum Build SFS (S-crounging F-or S-craps)

Is that a triple bolt pattern rotor? What size and ballpark price for the kit?
The number of holes = 15 which is 15/5=3 so yes triple pattern. 12.19" diameter and can't share the price as it was a wholesale closeout for dealers only--but it was WAY under a grand CDN $$$. J.Rob
