Back fastener on Thompson top won't stay tightened.

[gaC5]

I have the one piece Thompson transparent top on my 78. The back fasteners won't stay tightened and I get a lot of air coming in on the highway. I tried contacting them but just get the aswering machine. Anybody had this trouble and know of anyway to fix it?

Is it stripped out???or pulled away from the top???

It's not stripped out. I don't know what u mean by pulled away from the top.

the bolt is fastened to the top somehow...
is it pulled away from it,whether glued or embedded into the top...

The fastener is bolted down ok. It's after you tighten the knob that makes the top fit tight stays loose.
