[TR] Windshield tenax fastener fixing..

[Kinderlehrer]

I was able to fix this problem using a thread-serter or nutter. Kind of a 
pop-it riveter tool only it inserts a threaded sleeve.  Habour freight has 
them http://www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=1210 . 
I seem to recall I may have had to "work" the tool a bit because there is 
not very much depth, but that insert is holding as tight as any of the other 
studs and it's been quite afew years.  It worked for me. maybe some of the 
frames are different, but on mine there is enough room for the insert.
