Sold the boat with the Whipples. These are the parts I kept onboard for good reason as I broke pulley's off left and right til I used the new designed studs from Whipple. The upgraded one from ARP is the black one which is better than original but I broke these as well. See the new designed studs are silver ones they are longer and bottom off in the shaft and prevent torque shearing failure.(caused me a lot of hour long idle sessions). Also a spare snout ventless design. Vacum acutator. They go out often. Whipple gets over $80 for each stud.
Snout $100
Newer Studs $40
Vacum $40
