When I did mine a month or so ago I took out a good chunk of material from the botttom of the MAF support w/ a dremel and rounded out those edges. Good thing for you is that they greatly reduced the size of the support in that area on the Series 2 L67 TB, so you will flow better than me even where mine is now.

Take a look and you'll see how yours is better designed:
