"Oh, and the part numbers on one of the lower don't exactly match up with what the book says or at least I don't think they do. I may clean it more later to see if I can read more of the number."
Any number on a part is not a part number. See our page here: Documentation/How To Decode Ford Part Numbers.
But the short version is that #'s on parts are ID or engineering #'s and you have to use a cross reference to get from those to part numbers, which are what is listed in the master parts catalog.
I know it doesn't make sense, but that was not one of Ford's "Better Ideas".
The upper and lower insulators/bushing/mounts may be hard to find. But you may be able to find other bushings that will work. I'd look at the cab bushings and radiator support bushings to see if they are about the same size.
