I mounted my toyo box a bit unconventionally. I mounted mine up in front of the axle. I was going to make my own pitman arm by cutting off the spline section and fitting it into a chunk of 5/8"x2" flatbar and then welding it in place. In the end I ended up having to cut my pitman arm in two and reversing the ball end before welding it all back together......yes, I did have a certified welder do the work who has had lots of experience with this sort of thing.

If you want a tapered whole for a tie rod you can buy tapered reamers to do it yourself.

You can kind of see my pitman arm in this pic;


Here's the rest of my steering;
1949 Ford F1 4x2 - steering details

Having the steering box up in the front is not optimal and probably introduces a bit more bumpsteer than the original location due to the steering box being in front of the axle and on the end of the leaf spring with the shackle.. I'll move it eventually when I go to install my 63 Riviera steering column
