Abstract: The present invention provides a mounting fixture for mounting a vehicle body to a support member or vehicle frame. The mounting fixture includes an upper and a lower assembly attached to either side of a non-circular aperture in the frame member. Each of the upper and lower assemblies includes an elongated tubular member and a flange portion extending therefrom wherein the lower tubular member is received in telescoping relationship within the upper tubular member. Upper and lower cushioning members are positioned over the upper and lower tubular members and between the flanges and the frame member to provide a cushion between the frame and the vehicle body. The upper cushioning member includes a non-circular extension corresponding to the shape of the aperture in the vehicle frame whereby relative rotation between the upper cushioning member and the vehicle frame is prevented.
