www.arbcanada.com has OME stuff. I got my dakars, coils and other OME odds and ends from them. They were super unorganized when it came to relaying info to the freight company, but Tony (the owner) got it all worked out and everything arrived.
I got my billy shocks from downsouth motorsports. They only charged something like $50 to ship all 4 shocks. I couldnt find them cheaper anywhere.
I got a few little pieces from Wheelers and Toytec, but their shipping was too expensive for anything heavy or large.
