Re: f100 steering box conversion for model a
The Tradel book says this; cut the flange off an empty A steering box as close as you can get to the outside and still have some of the gussets. Cut the flange off an empty F100 gear box, about one inch from the gearbox. Grind a bevel on both parts. Sub assemble the gear box and install in the car with the body on to clock the two castings. Tack weld in two places. This is not cast iron, its cast steel, and it welds really nice with a home MIG. Put the gearbox on the bench, and really lay some heat in for about an inch, then imediatly do the oposite side. Walk away for an hour. When you come back, if the shaft turns easily, weld two more places. When mine was done and assembled, I filled it with straight STP and it never leaked, even with no seal on the shaft. The reason you want to shorten the gearbox is for clearance to install the V8. The shaft just sticks out an inch further, so what?
