Manual and power Saginaw boxes share the same frame bolt pattern (though manuals are all three-bolt mounts). So, if you’re swapping Saginaw-to-Saginaw, it’s a bolt-on conversion. If not, off-the-shelf steering box brackets are available for most Jeep CJs, even the early ones. The ’76-’86 CJs have stamped-steel brackets that prove vulnerable with big tires and hard use, so getting a heavy-duty steering bracket like this Sam’s Off-Road unit (left) is a good option if budget permits. The 1⁄2-inch-thick steel dwarfs the thin factory bracket.
