So I just installed my passenger side CRL vented window. A little nerve racking, but came out fine. I measured everything and it appears that dimensions on the drivers side are identical to the passenger side as well as being symmetrical side to side in the door. I'm thinking one could just flip around a passenger side window and use it on the drivers side? Any reason why this wouldn't work.
I checked that link and cannot find the part number for the drivers side sliding door, as requested by the OP. Are you installing the Fixed Passenger Side Window that you bought to a drivers side sliding door?
I just ordered the FW385R fixed window for the passenger side slider. The stamping for both sliders is in the same spot and symmetrical front to rear so I'm pretty confident it will fit. I have the T vent on the passenger side. Will update after the install.
So my window has been sitting in the box for the last 2 months since it's been raining pretty much non stop. Finally got some nice weather today and installed the window in the drivers side slider. Double and triple checked with a cardboard template and finally started cutting. Indeed the CRL FW385RFG passenger side sliding door window fits in the drivers side sliding door perfectly. I now have the CRL T vent in the passenger side and the fixed glass on the drivers side slider.
