Does anyone have or know where to find diagrams or pictures showing the differences in the 1/2 ton 3/4 ton 1 ton and highboy chassis / suspension setups?

 

You don't specify what year of trucks you're talking about, but if you go to your local library, the big Chilton or Motor manuals for the apropriate year range would have something. The smaller Haynes manuals for specific years should have something - try a used book store for used copies or your auto parts store for new ones.

Best source would be the proper shop/parts manual for the year of truck you're interested in. I am sure that our host - Motor Haven would have those.

67-79 are the years i am looking at.
