No no. Don't just install and go. You are better off cutting that down to be on the safe side.

At least do this; put the diff in (without installing the bell housing) and see if it hits when you slowly spin. Keep in mind that if it comes real close, then it will prossibly hit. There is some slight flex in all those parts when you put pressure on the set-up.

And that is sharp metal vs little baby plastic piece.
