I think comp and lunati are the same because my machine shop told me to call them to see about a fit for the spudmasters and the same damn music and message on hold. Exactly the same. 1 hr 45 minutes yesterday afternoon, down to 2 callers left in que and they closed. Please call back tomorrow. Then today I call 5 minutes after they opened, 1 hr 2 minutes in and boink! Hung up. I'm glad I don't live near there.
Summit guided me to the trickflow springs but still a lot of work if they will even fit in the seat.
The whole reason for the cam was to have enough vacuum to use the power brakes.
