Speaking of pitman arms, we ended up using a heavy-duty pitman arm from Sam’s Offroad. This beast of a pitman arm is made from 7⁄8-inch A36 cold-rolled plate steel (PN SOR-PAB, $139.95). We got a blank arm so we could determine the length of the pitman arm and drill our own tapered hole as we wanted. We ended up drilling and tapering the arm from the top. This makes sense for our Willys, which we are trying to keep low and stable.
