If you have the windshield out make sure to

[Michael C Henry]

If you have the windshield, out make sure the side mounting holes (10-32) are full good threads. If not Heli-Coil those holes to take advantage of full threads. My windshield has been in out and has been operating with some screws that only unscrewed one and a half turns till they came out. Probably short, not having enough threads contact so the threads gave up. The Heli-Coil can be trimmed so they will fit the chromed windshield side brackets depth.
My windshield frame appears to be chromed aluminum, not very though. SS Heli-Coils coils can be trimmed to match the thread depth in the windshield side frames giving lasting threads that will actually hole and not go to crap. And then you can trim the screws to fit and still not touch the glass. Removing the side frames one at a time can then be precisely drilled and threaded on a controlled fixture like a drill press. There are now other brands thread repair kits using coils.
