See the G Force Crossmember Overview for more info.

This transmission crossmember is installed with the transmission mounting tabs positioned towards the front of the car and so that the exhaust clearance humps are closed on the top and open on the bottom.

If you need them, aluminum spacers are provided to customize the height of your transmission mount. Position them between the crossmember and the transmission mount. Use longer bolts to insure full engagement into transmission mount.

Some applications will not require any spacers. Some vehicles of this generation are equipped with a transmission crossmember that bolts directly to the frame rail, while others are equipped with crossmembers that utilize tab that sits on the frame rails and are embedded with a rubber liner. The RCAEC2-4L80 bolts directly to the frame rails using the factory frame holes. Do not use the rubber liner. Instead, use the provided 7/16″ hardware and enlarge holes in your frame rails with a 1/2″ drill-bit. If you choose to use the stock size 3/8″ hardware, it is strongly recommended to use new Grade #8 fasteners to compensate.
