1973-1977, hardtops (note: distance between crossmember frame holes is approximately 51-1/8″. Measure your frame or crossmember to insure proper selection) note: will not fit 73-75 EL Caminos with the boxed frame rails.

installation notes:

• this crossmember is installed with the G Force label facing the rear of the vehicle.
• the crossmember is installed so that the exhaust clearance humps are closed on the top and open on the bottom.
• to utilize the provided 7/16 hardware it is necessary to enlarge the holes in the frame rails with a 1/2″ drill. If the installer chooses to utilize the stock size 3/8 hardware, it is strongly recommended that the installer obtain Grade 8 fasteners and washers to compensate.
