Doug, I was under the impression that the "ventshades" you purchased were the adhesive external type, available from AVS (Auto Ventshade) under the AVS VentVisor brand, but maybe I'm wrong--or did you end up buying the MacNeil product after having a problem with what you bought originally?Bought a full set for my wagon.
Front ones fit fine.
Back ones don't fit - without trimming. It seems the door frame may be just a skosh smaller than a sedan? Sedan rears [visor/shade] slip right in; it was a fight on the wagon.
Without the trimming [my learning experience], the back ones end up 'bowed' when installed. I ended up cracking the right one trying to get it in.
Yanked the back ones - and may one of these days try again - with a box cutter knife on a new set of rears.
Your fit may vary. But both my rear doors produced the same 'bad/compressed' fit.
