I have begun hitting the local junkyard for parts. I have never seen any Wranglers (YJs or TJs) or CJs before, but they recently picked up a ’77 DJ-5 (postal jeep). First thing I removed was the steering column, intermediate steering shaft, steering wheel, and blinker assembly that was attached. (I was only charged for the column.) The next trip netted me a battery tray and I also picked up the emergency brake pull in case it would ever come in handy. (It is not a standard CJ-5 one. This one is a lever.) I’ll be going back and picking up more from the DJ5.
I actually keep a database in my iphone for parts to look for. I still need axles, a underhood light, and many other parts. This junkyard maintains their vehicle inventory online, so I can see what they have and the row number while I’m walking around. It’s quite handy.
