Buchanan will build you a 21" front wheel.

It will take about 4 weeks. Leave the rake alone. Its more of a hassle than its worth. Fender? Pure preference. I left mine off. In fact I ground off the mounting tabs on the lower forks before I chromed them.
You will need to cut the fork spacers down about an inch and/or purchase a Progressive front spring kit.
Handling. It will take some getting used to. Front will feel heavy.
You are looking at $500-$700 for the whole conversion. If you do it right.
