The  wishbone that sits in front of the motor and provides a tremendous amount of support was hacked off.
The spine (top frame rail) needs to be notched to provide room for the spark plug and cap.  It looks like this motor was installed at a lower angle so the spine didnt have to be mod'd.  Lots of people did it this way before hybrid pipes were being made, however, pipes specifically made for hybrids wont fit.  The bottom boltrunning through the motor to each frame rail needs to sit on top of the rails and not run through the middle of each rail.
