wiper – glass of full poly ?

just looking for some clarification before ordering a wiper kit. i have the Polaris full poly click & go windshield Item #2879446 & want to buy a wiper kit. some dealers are saying it only fits with the "glass windshield" Item #2879447 but looking on line the glass frame & poly frame look the same other than one is glass & one is poly is that true ? . if its the fact that the poly will scratch , im fine with that , its 3 years old now & its time for a new one anyways in the summer. can anyone tell me if the wiper kit will in fact fit & bolt up with the full poly frame ?

thanks
