hydroboost unit fitment ?

[sweetk30]

i see there is specific part #'s for these .

i have a real clean uni from a c-10 diesel truck with good hoses .

want to swap it in place of my NASTY / RUSTY / READY TO POP lines unit i was going to use from old truck to new .

i dont recall much of any info on how there different from each other . there both from 80's gm trucks .

anyone know the difference or if you have a 1/2 ton unit on a k30 with k30 master and no problems.

i have a new master to install on the unit when i install a good non rusty/crusty unit .

I'm about to put hydro-boost on my 85. I have 3 systems-all mid 80's. I had pulled some units off of military 1009/1028s. Those were the Blazer and k30s. The units themselves are exactly the same. When I put the axles in my K20 they had much bigger brakes (Dana 60/13x4 drums). The only difference I found was with the master cylinder and it's bore size. All the hoses and fittings were the same between the Blazer, C30, and K30.

you look them up for each part for specific truck and there separate part #'s for the hydroboost unit .

I got two friends that have them on thier cars with big nasty engines that don't produce any vacuum. One of them we pulled off an astrovan. I don't think there's any difference in the unit themselves. Just match the master cylinder and go for it.
