I was hesitant in installing my windshield due to some of the threads that I have read where they mention it is a multiple person job. Well I set up some friends to help me out but they slept in and due to me being impatient I figured I would use a ratchet strap to hold the window and press it in a bit... Eureka- It worked.
I am not sure if anyone has tried this but I thought I would share.
