Sorry for the delay in replying. Did you solve the vibration yet?
The passenger side mount centers the engine. You will see the two mounting holes are slotted for adjustment. Loosen the two bolts and use a pry bar to move the mount as necessary. Assuming it didn't vibrate before you replaced the mounts, you know it has to be related to them. You might have to try trial and error in sliding that mount around. Look at the driver's side mount to see if it is centered. It slides on a square metal tube, about 3/4" square and about three or four inches long. You'll get a vibration transmitted to the body if the two metal brackets are rubbing against each other. They must be isolated by the rubber insert. If the brackets are rubbing, it's the passenger side mount you have to adjust to slide the engine sideways.
Once those two mounts are adjusted, look at the center front mount. The part that bolts to the core support under the radiator also has slotted holes. Check that the rubber isolator and bracket are centered in the bracket bolted to the body. You'll need a pry bar to move that bracket too.
As a point of interest, the Reliant and Aries K-cars have a front bumper that is tuned against engine vibration, and there is a rubber insert holding the steering wheel. Those two things are very effective in dampening engine vibration.
