I'm working on a 23" too. So far, for a chromed aluminum wheel, Colorado Customs offers just about any of their styles (3.75 wide) as complete bolt-on which will work with your stock axle and spacers and brake rotor, for about $1600. No need for a bunch of dinking around. They can also furnish it with a tire mounted and balanced for about $250 more. No fender, that would need to come from another supplier.
On my 2006 WideGlide, I can just slide the fork tubes up in the trees to compensate for the 1" increase in ride height. Don't know about other years.
I believe I also have a little of the rake in the trees, which might help keep the front end geometry from going too far out of whack. Don't know about other years on that either.
