Seeing as more and more parts are now becoming NLA from Toyota, i was thinking it might be a good idea to start buying some items off of trucks that are being parted out while i still can, I'm making my own list, but i wanted to see what other mud members would buy for a rainy day? Maybe a back up engine computer, a backup MAF, trans oil cooler, or maybe something as simple as a plastic windshield washer tank? What would be included on your list?
