iflywhenican,
I did open it up all the way and there is nothing in there at all. It's hollow or the fiberglass is just plain seperated. So that being said, they are very vague on the description since in one sentence it says 3/32 steel and another sentence it's composite BUT it's fiberglass.
I'm nervous about the replacement gear. The picture shows it to look exactly like the stock gear but the description shows 1/4 aluminum. [

Please let me know what you find out when you give them a call. I just got to my office and have to play catch up for a few hours since I was off for the last 5 days. You can point them to my pics
