This Interloc aluminum body mount bushing kit retains stock height between the frame and body. The bushing indexes and sandwiches the frame via two piece design. Hardware and the radiator core support are also included. Installation is simple and only requires a couple hours. If you are using a subframe connector with the body mount bushings, the body mount kit part number will change. Please look at gwc2-809 or gwc2-819.
FYI- GM in 1982 removed body mount bushings between the cross member and body and bolted the cross-member direct.
