Lou:
Based upon my 3 ERA experience, I recommend that you follow Bob's advice and cut off the bottom of the bell housing. Remember, it is a foot or so further back from the front wheels than the pan and therefore is more likely to catch something if you go over a hump or crown (say a railroad crossing) etc.
Frankly I would also strongly recommend that you go with the standard Canton or Aviad pan as recommended by ERA. They hold plenty of
oil (with
oil cooler and remote filter even more) and there is less chance of knocking an expensive hole in them.
Lose the "deep" pan.
Words to the wise.
