Interloc bushings from Global West Suspension are designed to replace the factory bushings for the 1967, 1968, and 1969 Firebird. They feature a self-locking design that sandwiches the frame and holds it in position. This design eliminates frame to body slippage. They are strongly recommended if you are installing a subframe connector.
Global West supplies six Interloc bushings with each kit. This includes two radiator core support and four main body bushings. Kits for use with Global West subframe connectors come with four bushings (two core support and two front body mounts). The rear two bushings come with the subframe connectors. New hardware is included.
