Looking for a dual 8 rib crank pulley or a stack-able twin 8 rib pulley solution. Needs to be 3 bolt pattern to bolt on front of an ATI 918485 Hellcat 10% over driven damper. Shallow as possible, mounting low mount AC pump and alternator on opposite sides down low almost even with damper. Want them on separate belts as each will be custom mounted to motorplate.
