The G Force Performance Products RCG-350 is a transmission crossmember engineered for 1978-1988 GM RWD G-Body vehicles. This crossmember is designed to fit a range of transmissions, including the TH350, TH200, Metric 200, TH250, Muncie, T10, Super T10, Powerglide, and Saginaw. Constructed with a durable black powder-coated finish, the RCG-350 includes all necessary mounting hardware for installation. It has been redesigned to accommodate the double slot bolt pattern found on standard transmission mounts, and G Force recommends using their GMTM transmission mount, sold separately, for optimal fitment. Installation details note that for use with the provided 7/16″ hardware, the frame rail holes may need to be enlarged to 1/2″. Alternatively, using stock 3/8″ hardware is possible, but new Grade #8 fasteners are strongly recommended for enhanced durability.
