As it is a vehicle (And light gun) specific wheel you may have gathered that those that have them in the US keep 'em.

Its far easier to look in the UK and ship from there. You will get used to doing that with a 101 anyway so you may as well start now.
Its not too expensive if you make sure the tyre is not mounted.

The other option is to go and make friends with he Mog crowd and buy a set of rims from them giving you larger wheels and more ground clearance although they are not very pretty to look at.
