Difference between C10/C30 master/booster!

[syncrov69]

I have to install a master cylinder and a booster on my C10 1971 because the previous is not functional. I would have available a set of master cylinder and booster from a 1971 C30 and it works very well. Is what he could do on the C10? If not what is the difference between the 2 (C10, C30)? I include a picture of the C30 master/booster.

the C20 and C30 masterr cylinder is plumbed oposite of the C10.
I can never remember if the C/10 has it where the front feeds the front brakes and the rear feeds the rear brakes, and then it's flip flopped on the heavy trucks... or if it is the other way around.
Either way, they aren't the same.

You can get one at the parts store for like 10 or 20 bucks though, so it's cheap enough you may as well get a new (reman'd) one

You can use the c/20/30 booster, but like Longhorn said go get a C/10 master.
