I don't have any wider axles in stock but have a few sets of spacers. i have some really nice 1" aluminum stackables, they retail 110.00 a set and i'm selling a set of 4(2" each side or 1" all of the way around) for 100.00 shipped. i also have a pair of +1" durablue composits without the spacer studs(if you run them in the rear, you just get longer studs/bolts at your local bolt shop)for 30.00 shipped.
Another option is to get different offset wheels as well.
yes, you can also flip the wheels, just measure the valve stem hole and drill a new one on the other side of your wheel, then either have someone tig weld the old hole or for the budget build, reinstall the valve stem backwards.
