some pictures of the inlet installation. Basically you ream out the holes for the inlet. Slide it into place. Cut off excess and get to your fill material. I used west systems, microballons, bondo, K38 mixed with microballoons. I'm still not crazy about the job I did and just puttied up some more to sand off later just last night. I'm totally unafraid of body work and don't mind adding and sanding 100 times if that's what it takes to get something smooth. The end result is always acceptable to me even if someone else could have done better.
The spar receiver is shown to make sure that you don't get the wrong angle on the intake. Someone installed theirs and had to redo it cause the bypass wouldn't fit between the spar receiver and the intake. Whoops.
