Roy Wallace has made up door seal kits for the FC Jeeps.  The kit includes all the rubber seals for around the door and all the window channel material for the roll down window.  It also includes the inner and outer window seals that mount to the top of the door and keep the elements out.  The kit is for both doors and is available through 1st Gear Off-Road.  Check out their web site below.
