( Note : Distance between crossmember frame mounting holes is 53-5/8″ inches. Be sure to measure your frame FIRST ! Before you order, to insure proper selection.)
Part #RCAE 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.
