Default Early 80's Vibration and parts diagram

I am new the the golf cart world. I just purchased what I believe to be an early 80's ezgo gas marathon, pics attached. no id plate. has a robins ec25-2pg motor with oil feed tank. it runs and is drivable. The main issue is that as you get to full rpm the belt does not go all the way out to the top of the clutch and it vibrates extremely bad and seems very loose. The belt is a 1-3/16" x 45" od. I have also noticed that the motor seems to move as you accelerate. from the picture I have seen in the 85 manual that has been in the forum it looks like there is a flat plate mount on the rear suspension that needs replaced? pic attached. Any thoughts on other issues it could be? There are many things I plan on upgrading on this so any parts breakdown so I know what is what would be appreciated.

There should be an engine ID tag somewhat under the S/G on the cylinder cooling tin, it'll tell you what year it is IF it's still there. Looks like this, the first two numbers after the 'MOTOR NO.' is the year. In this case it's an 85

I've an 83' and just replaced the motor mount bushings to help with that same issue. Seems to help take care of the vibration.
