Abstract: A support for mounting a vehicle chassis on an alignment bench. The support has a threaded bushing telescopically received in a sleeve fixed to a carrier arm. In use, the axial length of the bushing and sleeve assembly can be adjusted so that when received between the side walls of an attachment bracket for a vehicle suspension component, they lie closely adjacent to and preferably bear on the side walls. In use, the shank of a bolt is inserted through the side walls of the attachment bracket and the bushing and sleeve assembly received between them and is preferably retained therein by a nut received thereon. When desired, this mounting support permits the vehicle to be pivoted relative to the bench while still secured thereon by the support.
