Don,
The frount has an extra steering stabalizer mount that is not being used, take it off !!! I would replace the rear springs and eliminate those blocks. If not just replace the U-bolts with some thinker ones, those look a bit small. Also check the drive shaft carier bearing, it sucks when they go out !!!
Do you know what size wheels those are ???? What size tires also ??? I can help you out on BF Goodrich tires !!!
You can call any time !!!
Jim
BTW - Nice truck !!!
Does it have an overdrive buttom on the dash ???
