Replace or Repair? Soft top.
 

My back glass window on my '93 Miata tore apart from the zipper. It seems that all it would need is to be sewn back on but when I took it to get an estimate, I was told the entire top would definitely need to be replaced.

Has anyone else had a similar issue and have you been able to simply repair the zipper/window or do I need to replace the entire unit?

Thanks!
