Abstract: An engine/transmission mount for a vehicle including first and second brackets, the first defining an aperture, the second having spaced legs to either side of the first bracket. An elongated bar which has ends adjacent the legs and extends through the aperture is radially expandable whenever the legs are flexed toward one another by selective application of compressive forces on the legs by operation of a compressive fastener. While prior to operation of the compressive fastener the first bracket is free to slide along the elongated bar, radial expansion of the elongated member fixes the first bracket in a desired axial position.
