A squarebody cab should stay where you bolted it. Whiteline W93495 replaces the tired body-mount cushions with twelve black polyurethane bushings rated at 85 durometer. The linked Z5753 guide identifies six 90283 and six 90284 bushings; it calls for reusing the original shims, bolts, nuts and washers. Inspect that hardware before the first rusty bolt becomes the afternoon’s main event.
This listing covers 1981–1986 Chevrolet C10 applications within the supplier’s exact trim and engine rows. Match the original mount locations and hardware before ordering; the bushings do not establish fit for a swapped cab or modified mount arrangement.
Whiteline recommends a suspension specialist and estimates five hours. Its guide services one side at a time, requires clearance checks around the fan shroud and brake lines, and calls for a 500 km fastener recheck. Follow the vehicle workshop manual for support and torque. A wheel alignment is not listed as required for this kit.
