This should work! I have not had the experience doing it YET, but I plan on installing then 76 and later windshield frame on my 75 to do the same thing. (Use 76 and later tops, accessories, etc.)
I posted the same question on JU and everyone seemed to agree that it would work. JU is down right now due to some prankasters trying a denial of service stunt or I would post a link to the thread.
