67-71 door repair

[Eastonspeedworks]

Hi everybody my truck has recently developed an issue with the drivers door. The inner and outer skin have separated and let the glass rattle between them. I couldn't make the search function work so I was hoping someone had some advice on a paint less repair. I know it's a common problem and in 72 they updated to the screw but I don't know if there is bracing to fasten to inside the earlier doors. I'm unable to upload pictures for some reason but you guys should know what I'm talking about
