I'm new here so I apologize if this has come up before and already answered. I want to order Ventshades for my wife's '11 Panel. Any Ventshade ad I've seen is for the 4 door window version. They say they're not compatible with the 2 door Panel version. Is there a dimensional difference in the front doors?? Thanks in advance for any constructive input...

 

All front doors are the same, for all years and models of the HHR.
I believe Weather Tech has just a front pair available

The reason is that they fit in the window channel. They are sold at that site as a set of 4. Panels only have 2 side doors with windows. Therefore, their kits do not fit panels.

 

... unless you want extra shielsd for some reason.
