Chevy II Renovation, Part 2 Photo Gallery
Note the contrast between the stock suspension and the Heidt's pieces. Increased strength is a major benefit. The stock upper shock mounts attach to sheetmetal; the new coilovers will mate with a stout tubular shock bar. The four-link setup will locate the new diff much more effectively than the single-leaf springs--and that's not even mentioning the box-section steel subframe connectors.
