Vacuum take off point. 1971 6 cylinder 245 - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hi all.
I am working on a 1971 C10, 6 cylinder 245 engine, 3 on the tree.
I am looking at brothers power brake conversion.
Does anyone have information on this. I assume there is a take off point for manifold vacuum. Where? Also in the dash is the vacuum gauge, but it is not hooked up in the engine compartment.
Any info would be greatly appreciated.
Cheers
Mike

Right below the carb there should be a plug.
And fwiw you have a 250, not a 245.
You do know your air cleaner won't fit when you put a booster on.
Vacuum gauge likely needs to be tee'd in with the vac advance line on the carb.

Other than that, welcome to the jungle!!
You got pics of this truck?
