Did you get the 703s? I ended up going with those instead of the GX Overtrail wheels. I called and placed an order, was told they would come in late December, but they showed up this week.
I'm looking to buy a complete set of the OverTrail wheels from a GX550 in the St. Louis area. I'm only interested in the complete set of 5, including the spare. I'm open to shipping the wheels to me (using a secure shipping/delivery/payment method.)
