need help with booster

[Beto]

I have a 67 c10 and it has a booster but I'm trying to get a replacement, only problem is that it doesnt have any part numbers on it so I dont know what to order. I thought it was stock so I ordered a remanufactured one for a 67 from advance auto parts, but it did not come with a bracket and the mounting points are different.

So I'm thinking about ordering one from a 72 c10, but just wondering if it will come with a bracket?


Also whats the difference between the delco booster and the bendix one? Apparently theres two different ones that can be ordered, I dont know what to go for. This is starting to become a headache and I havent even gotten started on bagging it lol
