I just picked up a 72 C60 that’s been cut and shortened to fit a regular sized bed. It’s got the original big block 366, Clark 282 transmission, and Eaton 17221 rear axle. Since it’s all original running gear, the rear leafs are massive, and its got no shocks. It rides really, really rough. I’m brainstorming now how to modify the rear suspension. What have others done? Trailing arm set up? 4 link? I’m looking for ideas.
