i found a set of 84-99 style billet chrome wheels with tires at a good price. they are 21 x 2.15 and 18 x 5.5. is it possible to make these fit a 2006 fxst softail std. i did some quick measuring and the 84-99 wheels seem to be narrower at the hub. i'm worried that even if i get the right wheel spacers my front brake rotor and rear 20mm belt pulley will not line up right. has anyone ever made these work?
