Wide glide wheels on fxd
 

Would a set of spoke wheels from a 2000 wide glide fit directly on my 98 super glide. Or what needs to be changed?

Your rear will will fit with with minimal mods. You may need the spacers from the 2000. Not sure if the '98 pulley and rotor will bolt on to a 2000 wheel.

The front is big problem. A wide-glide hub will not fit in a narrow-glide fork.
