Technical Model A column drop?

Discussion in 'Traditional Hot Rods' started by rockabillybassman, Apr 24, 2013.

  1. I'm looking at changing out my column drop in my 28 A tudor. It's currently attached to the stock fuel tank mounting and it does not leak, but I'm pretty nervous about it. I'd like to change it out to a more sturdy setup. Anyone have any pics of how they mounted theirs? I presume they mount off the cowl cross piece (not sure of the name for it)?
    Cheers,
    Marty.
    BTW: this is my current setup.

  2. If it makes you feel any better(less nervous),I removed mine to fit a 36 dash and it was not an easy job to remove.I don't think you have any problems with it becoming loose or leaking.Just a thought.
     
  3. I've heard of A tanks leaking around the column attachment point, that's why I'm concerned.
     
  4. Mine leaked around the column attachment point in Project 29. I am about to make an all new "early Ford" style column drop for a friends Model A roadster (not Dale's). This one I am going to carefully weld a 1/8" plate into the bottom of the tank with some blind threads to bolt the column drop I make to it...

    If it doesn't leak, leave it alone...

    use a Column Drop from a 30-31 it attaches under the Dash Rail ( to the Cowl Crossbrace you mentioned )...... the 28-29 Mount is riveted and is a leak waiting to happen........My Dad modified the one in his Roadster to accept the oil pressure guage ( pictured )

    Note in Dave's first photo there are two sizes (lengths) of column support. They are part A-3520-E (short) and A-3520-F (long). They came out in April 1931 as a result of the tank leaks mentioned.

    The leaking column drop in my '30 pickup was so bad that it took the pickup out of service completely as it was dripping on my pants as I drove. A couple of years later, I am fixing up a tank for replacement and other problems showed themselves. Even though I do not like to tear down any running car, the fear of fire trumped that. Pickup is a very tight fit around my ample girth and the tudor is much more roomy. Good Luck: Fred A

    The 30-31 dash rail mounted column brace was the factory service part as well for earlier cars. Available for decades as a reproduction part.

    The longer of the 2 later supports corresponds to the early drop with the little extension piece, original in some bodies like tudor phaeton, commonly used as a modification in others where a lowered column was desired.
