    Hello, I picked up a 1968 peterbilt 359 dump truck awhile back. It started life as a log truck I was told. Has a small cam Cummins, was a 5+4 but unfortunately some one put a standard 10 speed in place of the 5. It's a bit rough around the edges but does the job, which is hauling in gravel and general farm use. The is my first big truck prior experience was just a 26ft freightliner fl60 and a couple fire trucks. I picked the Pete as I have always wanted one and figured I might as well get something I actually had an interest in/ wanted to fix up instead of something just to get the job done. First order of business is I have a leaking axle seal on the driver's forward rear axle and the shifter for my aux box stopped working on my 160 mile trip home. Well on to the picture, again a little rough but it should look better in a few years.

    dog beat me to it, I thought I was the unofficial welcome,,,guy, but welcome aboard. You'll find we're all bozos on this bus. Nice truck, and not just any 359, a "small window" to boot. '73 was the last year and quite rare. One thing, someone put a 10 speed in place of the 5? So it still has the aux. 4 speed box? Who do you think you are, Snowman? Just kidding, you didn't say what rear suspension, being a log truck, I would guess spring, or worse, if just doing local stuff, I wouldn't bother changing it. Leaking axle seals could indicate metal contamination, and depends how bad. Easy fix, and change the oil, it may look like metallic paint. Small cam Cummins, what 290, 335, 350? Good motors and flat dash? I had a '72 small window, was a heck of a ride. More pictures, and glad to meet you.Love the Pete :thumbup:
    Sorry for the poor picture, try this, my '85 daycab
