Hmmm.  I know that putting type IVs into an earlier body without the
bellhousing mount often resulted in the worst case scenario - a cracked case,
apparently just resulted from the extra torque twist allowed.....

Don't know about upright motors and I don't wish to put 'the mozz on'. 
However, I would guess some form a case cracking?
