Low Windshield

[<slowboy@cox.net>]

Need some help with a low windshield.

1. First, is there anything I should know about putting a low windshield and 
frame together? Or the things I should not do when putting it together?

2. Referring to the two sides of the frame: there are what look like rivets 
holding another piece of metal to the frame sides. This is where the 
weatherstrip attaches. I need to replace that piece of metal. What I don't know 
is where to get those rivets (if that is what they are) or a viable substitute.

Thanks!
