TRA-4220 installation notes:
Crossmember is installed with transmission mounting tab positioned towards front of car, and exhaust double humps are on the top, next to floor pan. The supplied aluminum spacers are to provide custom height positioning of your transmission mount. (if you need them) They are positioned between the crossmember and your GM 3 hole transmission mount. Select desired amount of spacers needed and 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 crossmember that bolts directly to the vehicles frame rail, while others are equipped with crossmembers that utilize tabs that set on the frame rails, embedded with a rubber liner. Our #RCAE crossmember bolts directly to the frame rails to the factory frame holes. ( Do Not Use The Rubber Pads ! ) utilize the provided 7/16″ hardware and enlarge holes in your frame rails with a 1/2″ drill-bit. If you stay with the stock size 3/8″ hardware, it is strongly recommended to use new Grade 8 fasteners to compensate.
