That is exactly how mine looks in the back, but in the front where yours is even with the front edge of the rib, mine is sitting about 1/4 inch back. I am going to leave it that way because it looks like yours in the back and I cannot figure out how it would work any other way. But, I will fill in the gap at the front to make it a little more aerodynamic.

THanks for the help and the photos.

I also have an OS 46AX on an Avistar. Great engine. I hope the TT46 Pro is as good. I think the TT is a little heavier.
