rear doors, 200/5k wagon

[EJKellock@aol.com]

Noticed over the weekend that the window frame portion of each rear door
appears to be loose.  The forward upright can be moved laterally inboard
about a quarter inch, away from the lower portion of the door.  Both sides do
this, but only on the rear doors, not the front.  My first thought is that if
I remove the door panels, I will find an attachment that I can tighten up.
 Can anyone confirm this?  I'm not in a big hurry to pull the door panel if
it's not necessary...

TIA
