Pete,
We fly off of grass, and I also put 3" wheels in it. The 3" wheels fit inside nicely, as I widen the wheel cutout on the sides to be flush with the left/right edge of the pants themselves. Makes it alot easier to get in there to tighten things up. Plus, I see more tire coming out from the bottom of the pants. Don't know if that means anything but I feel more comforatble about it. I also reinforced the wheel pants with strips of fiberglasss cloth and I replaced the hardware that holds the pants in place on the gear wire with Sig's hardware. Big difference there too!! The whole set up seems to be a lot tighter.

Anyway, I got the gear from Bob Shattleroe Custom Gear. GP-5 was the number. Address info for now:

Bob Shattleroe Custom Gear
out of Garden City MI.
Phone: 734/261-9064
Fax: 734/261-4242

I say for now as he mentioned at Toledo they are moving and they maybe out of action for a while. You can try contacting them but don't be surprised if you don't hear from them.

The gear is not cheap compared to the price of a new one from GP, but look at the difference in quality. I paid $33 and from the picture below I think you will agree it was definitely money well spent.
