Red face 1965 Impala vacuum lines questions

Hi - Im new to this site. I have a 65 Impala SS with 4 speed and factory air. I just got it- its very original and unmolested.
Its all intact but all the vacuum lines under the hood and the ones that go thru the firewall to under the dash inside the car are old and cracked and
in some cases not connected where they once were. So here is my situation -- I would appreciate if someone with prior experience and
knowledge of these vacuum lines on a 65 explain to me what is supposed to go where and the purpose of each one. I want to replace all
these lines with a whole new kit. Where can I get a kit and where does each one go. I got under the hood and under the dash and can see where most of them go, but I could use help from someone to coach me on all of it to make sure I have it all correct. My goal is to get the air cond working again and to have it all correct again.
Many thanks - John

Welcome to the Team John!

There is no kit that I know of. Your local corner auto parts store sells silicone rubber hose for washers and vacuum lines. They also sell plastic T's and other fittings you may need.

And, you are going to need the Factory Service Manual for the line routing and connections.

Two doors, four doors, wagons, and ragtops.

Below are all the links you will need to perform most anything you need to from front to rear: I suggest you download both PDF's and keep them as long as you have your car.
