I would probably contact JMC Motorsports in San Diego, Clifornia for the information you are requesting. Mustang Monthly did an article in the Sept. '03 issue, entitled "How-to: Reglue '69 Side Windows." The article can be found on pp. 48-50. I would attempt to contact Dave Toth. They can be reached at:
