I met a dude on the Ford-trucks forum who sold me a box for my '59 F100, with the provision that if it was what I was looking for I could send him a check. Trusting guy to say the least! Anyway, it got here yesterday and it ain't nothing like mine, though he swears its outa a '59. The pitman arm shaft has splines 360 and measures roughly 1.125, whereas my box has slines around a 1/4 of it and the place for a bolt to past thru the shoulder of it, and is 1.250. The column on mine slides over the outside of the box on mine, whereas it goes inside the box on his. Also, his is larger overall, the mounting bolt locations are different, hell nothing the same! Again he swears its outa a '59 F100. He has no reason to lie about it since I haven't even paid him for it. I'm gonna try and post some pics, maybe somebody will know the difference.
I just went and looked at my steering box from a '57 Chevy pickup (pulled it myself). The one that you show with the splined output shaft and filler plug at an angle on top is an exact match for it.
Also, I think you're gonna find the word "Saginaw" on the casting somewhere...they didn't work for Ford back then.
I don't see saginaw on it, but it has a guess a part#, 5667979. I'm fairly sure now its a chevy box. just my fuc*ing luck!
This look like it? Best pic I can find of a late 50's Chevy pickup steering box! This pic is taken from a Chevy parts supplier site.
Thats it. The guy had it in a f100 and said it drove fine. I guess I'll make it fit mine and do the same. Thnaks
