Finally about 1/2 way through with the 4th door in my quest to restore the guts and rubber gaskets and felt of each door. Should be done with that fourth door this week or weekend. Today I ordered headliner material to address the saggy headliner here soon. I'm going to remove the rear window to get the headliner out and either put the existing solid rear window back in with a new gasket or put in a sliding rear window. Haven't quite decided yet. A sliding rear window would allow more air flow throughout the cab and I've always been partial to a rear slider but we'll see what happens.
After that, the only major thing left in the interior is carpet and may upgrade the audio when I do the carpet. I'm going to address more exterior stuff before I worry about carpet and audio, though.
