The adaptor plate goes no farther down, that I noticed, Also the plastic bosses are on the outside of everything so they should be no problem.
They are a PITA to get the clamp lined up right the first time or two.
With the air box split in half it's not that bad. After a couple of times thru it your wonder what all the fuss was about.
Trying to think of anything that would be blocking, and coming up blank. bummer.
