The BEST place, hands-down, in the GR area is a place called RiverTown Hobbies. It's a smallish shop located in a strip mall near the intersecton of US131 and 10-Mile Rd. in Rockford. He has a good selection of Align parts and other things for a TREX.
I don't know if I would make that haul from Lansing unless you were really in a pinch, though. If you do come over, let me know and maybe we can get together for some flying.
If I were you, I would order a complete spare parts kit from ReadyHeli or something. If you do run to Rivertown Hobbies and you need something specific, you might want to call him first. His # is 616-863-3600, He almost always has "normal stuff" on hand, like shafts, blades and other things.
The only other palce I know of that "might" carry Align products is a LHS in downtown Holland. I don't recall the store's name and I can't say if they sell align, because the ONLY thing I have bought from him was a CX2. It WAS a pretty big shop, though.
