Hey Keith.
I really like my autometer gauges. I got them when the classics were the only ones made. I did upgrade to a 30 lb. boost gauge and made it match.
I prefer the full sweep style, mechanical gauges. Maybe they seem more reliable, maybe they seem more accurate, maybe I like the way they move?
I like checking engine temp with the key off. I really like the immediate response to engine changes the mechanical oil pressure gauge provides. So far no oil leaks from the nylon tubing, although I ran it in vacuum hose to protect it and hide it.
I have changed it to copper tube recently, still in vacuum hose.
I'm anxious to watch the boost gauge wrap almost all the way around going from 15 in/mg vacuum to near 30 psi boost whenever I get all my parts installed.
Just my quirky perspective.
Cheers,
George
