63-72 CHVY/GMC TRANSMISSION CROSSMEMBER

MIA's Description

The Brothers Trucks TCM6372 is a transmission swap crossmember designed for RWD 1/2-ton and 3/4-ton classic trucks. It mounts in the factory location and allows exhaust systems to be routed over the crossmember, providing extra clearance for lowered trucks. This crossmember is ideal for enthusiasts converting from older 3 or 4-speed manual transmissions to modern automatic transmissions like the TH350, TH400, 200R4, or 700R4.
