Good news, bad news. The good news: the air box fits great. I trimmed it up a little at a time and it will be a good fit. Bad News: I didn't read ahead when trimming the baffles, I should have not done the final trimming on the left air ramp (This little tidbit was hid in the FAB instructions). I have already ordered a replacement floor and #2 cylinder side baffle. On the up side, I was not happy with the fit of the original floor, guess I get a second shot at it.
You can see the lack of overhang (floor covering the FAB).
