I think I had the same problem - if you are talking about the pants over the wheel bracket. I haven't done the leg fairing yet but it didn't look as hard as the pants!
I haven't finished the nose wheel fitting yet, but what I ended up doing was putting the brackets inside and taping them to the side. I was then able to get them on the wheel. The problem I had was the tape holding the brackets on. Once I got them close, I drilled a hole and used cleco's to hold them on while I fitted them better.
I haven't finished yet so I can't say it worked great, but there was no way I could get the pants over the bracket. Good luck and post some pics when you get it figured out so we can learn from you! Thanks
