    Hi!
    I`m quite new to the Cadillac`s myselfe, but I think the best thing would be to get a service manual.
    I bought a -69 DeVille Convertible a week ago, and I`m waiting for the manual to be delivered

    A little mechanical freshening and the car will be good to go. Congrats on your new Cadillac!

    A good going over it wouldn't hurt. I'd start with changing out all the old fluids. Check your brakes to make sure they are not frozen up. If it has not been started for a long time you might have to drop your gas tank and get rid of all the old gas. In addition I'd pull the plugs and drop some motor oil down in the cylinders and crank it over a few times with the plugs out just to make sure your cylinders are not rusty. A friend of mine had to disassemble his old Mach 1 Mustang because it locked up the engine due to the cylinders being varnished into place. Hopefully that won't be your problem. Replace any old vacuum lines or hoses in general if they are cracked or dry rotted. Same goes for the tires. If you see cracks on the sidewalls they can blow out at anytime. I actually had an old tire do this just sitting in place in the driveway. Start out with small trips around town and you will start to figure out what else needs attention. Also use some sort of gasoline additive to compensate for the lack of lead and ethanol additives in todays gasoline. Run Super Unleaded. Have fun. You will probably never drive a more comfortable car. Think of driving your couch down the street.

    Go through all the front end before you drive it regularly. The weight of that 7.7 and six foot hood eats up 45 year old plastics

    You have a hole on the evaporator/heater core cover. Missing mix door actuator.

    The missing mix door actuator was mentioned already.
    I bet that hose connects to the missing air cleaner.
