    Guys,

    I am building a 35 Ford shop truck out of cast off parts and I am needing a steering box and column. I am looking for the smoother action and I have heard that the later boxes had improvements over the earlier ones. I am looking at a 1940 pass car with the column shift.

    What is the best box that will still bolt up in the 35-40 Frame? Will the later boxes ( say 1946-48) have the same footprint? I am thinking they are different but just want to verify.

    Thanks

    Root

    The 37-48 box is essentially the same box , the difference is in the length of the steering shaft and the mast tube for a floor shift or a column shift.

    Thanks Dick. Is there something in print that covers these differences in length?

    So, 35-41 will all bolt up without modification?
     

  5. You'll need a steering box mount from a '37-'40 car or '37-'41 pickup to replace the one on the '35-36 frame.

    Thanks.

    Is there that much difference (performance wise) between the 35-36 and the later 37-41 boxes?

    Yes the 37 up have the same style guts as the F-1 .
     
  8. The heavier duty boxes from the ford or merc 3/4 pickups...40's...would be better than the standard car boxes. They have a better ratio making them easier to steer.

    37-48 and F-1/F100 are worm and roller style boxes.

    37 & Up boxes are better. I have a 38 and a 40 that I can measure rod lengths on if you need it.
     
  11. The '37 and later boxes are vastly superior to the '36 and earlier boxes. They require less steering effort, and they hold up a lot longer before needing a rebuild.

    I think I should be ok with the 37-40 boxes. The longer lengths come in on the post 41 stuff me thinks....

    I just thought that would be the easiest. I have a saginaw 525 box I could use and throw a plain old hot rod column in it. Sounds like I am going to have to change the plate no matter what. Mac's has the plate for the later Ford box for $43.

    The 525 box you mention is far superior to the 37-48 Ford box. Unless you are after the looks rather than steering ease, go with the 525 box hooked to the stock column. An adapter is available from P&J and CE. I have two units done this way and they work like a PS box. Make sure your 525 is a 24:1 or 6 turns lock to lock.

    The '37-48 lengths are listed in the '28-48 catalog...you will find several common ones same length as the '35. Or just mesure from bottom of shaft through the lower opening to top end of shaft. Don't have the book here, but at least '37-40 should be about that length. Once you have total length, only remaining job will be to drill and tap a new hole for the lock collar to get it in right place for the '35 lock...copy original, or, again, that dimension is in the parts ID chart in the catalog.

    Thanks Bruce, I am checking my Mac's catalog as we speak.

    Research in catalog shows the '37-40 passenger car and pickup (NOT big truck) boxes, plus 1941 pickup/sd to have the exact same length as the '35, 46.5 iches total shaft length. There are a lot of part numbers in this group, all differing only in the location of the locking collar that engages the steering lock...so all you would need is to drill and tap that hole in the shaft to mount the lock collar at same point as the '35, or whatever column/lock you are going to use.
