I just went through this myself when I installed a rebuilt overdrive in my
1. You need to remove the starter before you pull the engine. Even then,
you do have to rock it a bit to free the mounts.
2. The square backing plate goes between the motor mount bracket (the one
attached to the body of the car) and the lock washer and nut which secure
3. When I reinstalled my motor, I left off the left hand backing plate and
the lock washer and flexible magnet (the kind that you get from the local
real estate guy, insurance agent, or cesspool service to put on your
refrigerator) to hold the nut in position.
In case you are wondering if it is all right to leave off the washer and
backing plate, this was the second time that I had installed the engine this
way and drove the car for seven years in between.

Subject: Motor Mounts
I am getting ready to install the engine on my 1980 MGB. When removing it
this summer, I found it very difficult to get the engine out because it
appeared it was wedged between the front motor mounts. In order to release
the engine, I used my hack saw and actually cut the rubber mount in two to
release the engine. I found 2 shim plates (each >1/8) between the motor and
top of rubber on the motor mount, In addition, I found a square backing
plate but do not remember if it was between the body and the bottom of the
rubber motor mount or if it was between the bottom of the motor mount and
the securing bolt. I have looked in my manuals and can not find where they
talk about the shims or the backing plate. The Moss catalog shows a plate
(91a) that goes between the engine and rubber mount. Could the addition of
shims been causing the difficulty to release my engine? Also, What is the
trick in installing the bolt on the driver side motor mount because of the
steering rod is in the way. I have installed the rack and pinion and would
rather not remove it unless I have to.
Any advise would be appreciated.
