None that I can remember, except for the ones listed on Tim's site. I know people have had problems with the forward mounts. I did not, but then again my brother-in-law was an F-16 sheet metal mechanic (now F-35) and for the most part he kept me from doing a lot of stupid things.
If you have problems, you can always buy pre-made HS1008 brackets. They aren't that tough, but at that stage in the build I did have to do it 2 or 3 times to get it right.
Dont forget to install the snap bushings for the trim cables.
Also, you can run a couple pieces of plastic tubing through the snap bushings while you have things open, and it will make putting the trim cables in a lot easier. Just insert the threaded end of the trim cable in the plastic tube, and let the plastic tube guide the trim cable into the stab. The plastic tube will come out as the cable goes in. A couple pieces of tape or safety wire will keep the tubing from falling out until it is needed.
