Need to Know Factory Vacuum Hose Setup For My Delco Brake Booster

[cericd]

I'm adding a factory Delco/Moraine brake booster to my 1970 C/10 as part of a front disc upgrade. I'm trying to hook up a vacuum line that will look as stock as possible.

My truck as a 307 and a stock 2 barrel carburetor. I've read on other threads that the port on the booster hooks up to a vacuum port on the back of the carb. Is that just on four barrel carbs?

If so, does it hook to the port at the back of the intake manifold? I always see a rubber hose coming off the booster in photos here on the forum. Does anyone have pics of a 307 with a 2 barrel and a factory booster so I can see what parts I need to get?

This is my booster.



Here's a pic showing what looks like a hard line coming out the back of the carb (not my truck or pic).



And here's a pic showing the long rubber hose I mentioned (not my truck or pic).
