This is the cowl steering set-up I've done on my model a coupe, here is a link to the whole thread http://www.jalopyjournal.com/forum/showthread.php?t=260588&highlight=dreadman coupe . I did cowl steering because I'm using a Buick nailhead engine, that didnt leave enough room for a F-1 or F-100 box. I built a "hoop" out of heavy walled 2" round tubing, that attaches to the frame with 6 bolts to ensure maximum strength for the steering box. Once I established, placement for the box (in this case a 1966 Mopar model), I fabricated mounts, so the box could be firmly fastened to the "hoop". Next step was to cut the stock pitman arm. All that's needed is the splined end. The "end" was then welded to a heavy walled round tubing, making sure the, the ID was big enough to receive the 1 3/16" socket, required to tighten the 7/8" nut. I can't stress enough, that if you have any doubts about your welding abilities you should consult a professional. The other end of the sector shaft was drilled for 6 holes and threaded, and the drilled to allow the socket to pass thru, again, this end was welded to the shaft. Again, this piece is only about 3.5" long, but is, just about the most important piece, safety wise, when it comes to cowl steering. A pitman arm was fabricated, out of 1/2" thick cold rolled steel. It received 6 corresponding holes. Then it was bent so the tie rod end would clear the body.
