I looked through your past posts but didn't see which model you had. If you have the Tourer (has hard saddle and factory windshield like the one shown at this site:
Windscreen), I would go with a Clearview like previously offered. Top quality, a bit thicker than stock, same mounting. You just replace the plastic and go.
If you have a Standard with an aftermarket windshield, then you will have to either replace everything (plastic and mounting frame) with a unit of your preference (such as Memphis Shades) or contact the manufacturer of your shield and ask for a replacement shield for your frame.
Hope this helps.
