    I've read everywhere about using a F1 gearbox on model a builds. My question is there a difference in the F2 and can it be used?
     
  2. Are getting confused with steering box? Or, do you really mean gearbox?

    According to other threads here, the F1-F3 boxes are the same and they get bigger after that.

    I have both. Was told by a old friend,in his 80's, who has owned ,collected, and worked on F-1's and F-2's, that the truck's have slower turning ratio, you will turn the steering wheel more to make the turn.

    UPDATE: The steering box pictured to the right turns out to be F4 or larger. Please disregard.
    I think the F-2 box is bigger. Here's a side-by-side pic that was posted in the parts for sale section a few weeks ago; according to the seller, the F-1 box is on the left (painted) the box on the right is F-2 (rusty).

    I saved the image because--presuming the seller's data is correct--the supposed F-1 box I bought at the Monroe swap meet a few months ago turns out to be F-2. But at $25 for box, column and wheel, I really can't complain.

    Here's a link to the ad--there's more pix: http://www.jalopyjournal.com/forum/threads/1948-1952-ford-truck-steering-box.987095/

    I see the physical difference. The only reason i'm asking is because I may buy a f2 for its motor. And it has all steering.

    That box is not a F2! It's a F4 or larger. F1- F3 are the same. I,m the one bought that box. I wanted the larger for my modified. It takes a larger Pittman arm.

    Thanks HD Driver, that is good to know. After seeing the parts info posted by fordfitrucknut, I was wondering if there wasn't something wrong with the description in that ad. Sorry, all, for bringing misinformation to the thread.

    I've seen a few f-3s in junkyards around here they were all big steering boxes... I have always believed f-1, f-2 were small boxes

    If you have chance to buy a F4 or 5 box, that's in good condition, don't pass it up. Even though there larger, they still are very useable, especially in a four cyl. application! But I would pass on one without the pitman arm. There very hard to find. The pitman can be modified by cutting of the ball and drilled and tapered ( 7 degrees) for a early style Ford rod end. More than enough material there. You can also fit a standard ford F1 steering wheel . Hope this helps out.
     
  19. Is the earlier jail bar steering the same setup as F1 to F4? Still trying to find info. Also the crossmember

    Makes sense. If i remember the od of the spline was 1.125. Vega is smaller than that.

    I'm confused! Wasn't the question ; is a F2 box the same as an F1? The answer is, yes!
