Can someone tell me how to remove the clear plexi glass from the wind screen bracket??

 

Are you trying to replace the short OEM plexi glass with a taller one from Rick Hesel? Rick had posted instructions on how to remove the OEM piece at one time. Do a search of Rick's posts and look for wind screen in the "S2000 Talk" forum. Otherwise go to Rick's web site and he may have it posted there. Good luck.
