Stock engine unknown mileage .
I’ve owned 15 of these trucks and never had to change a booster and have never heard one leak before .
I have checked the boosters with a mighty vac and they do not hold pressure . They leak down.
In past I’ve had issues with rock auto and they won’t return a email so don’t care for them.
Looking at trying one from national parts depot Chevy catalog now .
Thanks . Tried oreilys yesterday and it was ng as well . Up to 4 now .
Positive thing is labor time says 1.5 . I can do it less than 20 .
all the parts stores around here get reman the same part number from the same warehouse . They can’t get a new one .
Called lmc for a new one but they...
bought a 84 k10 and the booster was leaking around the pedal . So I changed it and still leaks . Been thru 3 boosters and all leak .
Am I missing something or just getting ng parts . 2 from napa and 1 from advance.
I tried auto zone here but they don’t know what a booster is or how to look...
It’s got a 203 In it not to crazy about that but it works may look for a 400/205 for later . Trans is a little weak but run and drives . He picked it out he wanted a auto.
