1972 c-20 with leaf springs

I have a 72 c-20 with leaf springs. It has the curved frame like the coil spring trucks so I am guessing I can use a regular coil spring c-notch for it? I was looking at the western chassis 2 pc if anyone has any better advice please feel free to advise.

Re: 1972 c-20 with leaf springs

C20 frames should be the same coil or leaf. It’s the 4x4, one ton, and Longhorn trucks that have the narrower spacing parallel frame rails. Can’t say I knew there was a different notch for the chassis types. Interesting.

Re: 1972 c-20 with leaf springs

I would agree with Mike C. My leaf spring GMC 2500 has the wider frame. You can see where the coil springs would go if it had them and I have the crossmember for the rear control arms.
