I picked an oem airbox at a parts yard out in (guess it was) San Bernadino several years ago -- thought I might need it for CARB emissions test/visual inspection (actually didn't need it). The yard seemed to specialize in Jeeps -- saw dozens of hoods, tailgates, grills, ...probably had a ton of YJ and TJ doors too -- just don't recall off hand. See if I can get you the name of the place/address. Only trick is, if they do have several pairs of TJ doors, a set would probably need to be painted to get things matched up.
