I have experienced broken engine and transmission mounts, mostly in '63 through '65 Imperials. The broken mount will cause some vibration, but not cause the engine to shake whatsoever. The broken rear mount can make the transmission housing shift position during a sharp turn. That is a very ODD feeling, but it only happens once per turn and would not be considered a "shake", at least not to me.

That sounds like it could be a bad engine mount. I've found that most often, it would be the one on the drivers side.Many times, the protective shields have been removed & the rubber gets soaked with oil. The drivers side of the engine will sit lower then it should & vibrate against the frame.

Here’s my 1st problem: Engine runs great, idols fine after it’s warmed up a bit but when you put in DRIVE it starts to shake, rattle and shimmy like something is loose. It’s not the motor supports. When you get the car going down the road it does fine.It’s only when I come to a stop that it shakes so bad, almost to the point of cutting off it’s so bad of a shake.
It sounds like a vacuum leak, and it's most likely a leak in the power brake booster. The booster can leak when you have your foot on the brake--as you likely would when you're sitting at a stop light--but then not leak (or leak less) when your foot is off the brake, as it would be going down the road.
The easy check is to tightly block off the hose to the brake booster and see if the engine idles better. Boosters can be rebuilt, and there are good resources for this listed under the Repair section of the website.
2nd problem: Air conditioning is working and blows cool air. But when you engage it you see and hear the clutch running like it’s loose or out of balance. Makes a lot of noise like a bearing problem.
First check to make sure the bolt in the center of the clutch is good and tight. Seems like a simple thing, but you'd be surprised.
Good luck!
