What engine/truck do you have? It is relatively easy to adapt Saginaw steering units, both inside and outside the frame. Different pitman arms allow fore and aft movement or left and right movement. One also must cut the shaft and housing and install a u-joint and support for the shaft and housing. The housing is usually terminated near the firewall.
