G Force RCB3-400 Transmission Crossmember, 1977-1990 B-Body, GM-3

This is Garage Sale priced because it is a factory shipped open box item and returned that we don't carry in house.

NO WARRANTY, NO RETURNS ON GARAGE SALE ITEMS

For all you Classic B-Body Builders, we've designed a direct bolt-in transmission crossmember to accommodate your swapped transmission while still using the factory crossmember mounting locations. No drilling, cutting, grinding, or welding! Simple and complete instructions are included, along with new mounting hardware.

NOTE: Many G Force Crossmembers utilize the early GM double stud transmission mount configuration, for the increased strength aspects. Should your vehicle originally be equipped with a single centered stud transmission mount, simply replace your transmission mount with the early style.

• Fits 1977-1990 B-Body
• Large exhaust clearance humps for large diameter exhaust systems

Since different transmissions can share the same overall lengths as well as other measurements, they can also share some transmission crossmembers. G-Force has grouped the transmissions together that can share the same crossmember.

This Crossmember fits the GM-3 Transmission Group:

• Turbo Hydra-Matic 2004R (TH2004R)
• Turbo Hydra-Matic 400 (TH400)
• Turbo Hydra-Matic 375 (TH375)
