Im only 15" taller than your tires.... 


me too Brett....needs Cary's hood tho!
Is this cab solid mount?
My 89 R3500 is aluminum w/plastic reservoir.
Yeah, it is hydroboost. However it fit the hydroboost from my 84 K5 just fine.
Interesting, if you look at C3500 instead of R3500 you get the aluminum master w/plastic reservoir. I also notice they list one with a 1.25" bore for hydroboost and another 1.125" bore which I assume may be the vacuum booster style.
how you going to run a vacuum booster?
I didn't think the 6BT vac pump was enough to run a brake booster, that's why they all have hydro? dunno?
Early 12 valves were not hydro, the 95 that my engine came from was a factory vac booster.
Gotta quit looking at this thread, getting anxious![]()
