Hydroboost and my ‘74 - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have an ‘89 1 ton with hydroboost and a ‘74 with manual brakes..

Looking at the ‘89 it looks like it should bolt up to the ‘74.. maybe?

I know I can buy a kit but how hard is it to piece hydroboost together out of rock auto? I’ll make my own lines so that’s an easy button. The brake rod might be an issue but I think that’s not too hard to fab.

Anything else I’m missing or something else I should be thinking?
