This universal crossmember bolts or welds directly to your stock frame rails and allows the installation of a TH350, TH400, 700R4, 200R4, 4L60, and 4L60E transmission. Manual transmissions can also use this crossmember with little modification. It is also helpful with relocating the transmission when power brake systems are used in the stock position. This crossmember is 30.5-inches wide and can be cut to a shorter length - if needed.
