I find myself hoarding parts for these trucks more and more. For example recently I was getting some oil seals at a parts store I hadn't been to in some time. Turns out they had some old National Oil Seals that were made in the USA. All I had seen as of late were mexico or tiawan seals. I asked how many they had on the shelf and bought all of them. Now I'm set for wheel bearing repacks. Just a few years ago I would have only gotten what I needed for the job. Now I'm thinking this may be the last chance to get these parts before they go offshore or on the cheap. For example if I had known they were going to discontinue the PF35 I would have bought a lifetime of oil filters. Any one else doing the same?
