Installing my new SBT engine in 2004 F12, I did not remove the Drive Shave Bearing Housing, but did remove the pump to have impeller rebuilt.

The manual references using a special alignment tool to be used when re-aligning the engine to pump and it is part of the instructions for re-installing the motor.

How much of these alignment steps are needed to replace the motor if the Drive Shaft Bearing Housing is in original position? Are there other techniques that do not need the special tool? I don't want to bypass an important step, but this step is holding me up from the water!!!

While I am at it:

- If I need the alignment tool, where is a good source?
- Where is a good source for engine mount shims?

Thanks!
