I have the same windshield on my Roadster... If the windshild is installed the same as mine there is a rubber seal at the bottom that has a sealer... When I removed my windshield to repaint the car, I had no trouble getting the glue of of the paint without messing up the paint... However I think you will find that your current windshield frame mounting holes are not in the same location as the factory style frames... The measurments I have taken from mine show that the old holes will not be covered by the stock windshield frame...
