[Tigers] engine mounting brackets

[Owain Lloyd]

there are 3 bolts that go from the wheel arch and hold the cast steel
engine mount brackets to the frame.  one of mine is loose and will not
torque up.  where is the threading for this located?  is it a welded
nut in the frame rail?  if so, i'm not sure how that holds the bracket
on - is the bracket itself threaded?  any suggestions on a way to deal
with this without pulling the engine?  if its the bracket thats
threaded could i safely tap the hole to the next size and use a larger
bolt?

thanks.
