Buying from afar

For me my hands are a mess so reaching up inside the dash and undoing all those screws is a pain. A lot of my research points to old lubrication drying out and creating friction spots. Some people use wd 40 do dilute and flush the old lube, and replace it with a very light oil like white mineral oil. I happened to have some synthetic clock oil which has a fantastic shelf life and is pretty cheap on Amazon.
