    Think the torque tube on my model a is upside down.. the cut out for the speedo drive is on the top. Is this right? Why would it be turned over? It was this away when I got it. Should I turn it over?

    Thanks! This is my first car with an enclosed driveshaft. And I thought it was supposed to be on bottom.

    It's an old used car dealers trick....turning it upside down runs the odometer in reverse...the miles keep lowering.....:D

    Unless I am misunderstanding the original post, I would disagree with #2 post.
    On a stock Model A the cutout for the speedometer "turtle" faces the ground (as does the turtle) with the speedometer cable entering the turtle from the passenger side of the car. The rear radius rods also bolt to the front of the torque tube through a boss on the lower front of the tube.

    If the rear suspension has been modified, an upside down torque tube may not be important.

    Peace, Phred

    PhredH, is correct. The cut out for the speedometer gear cap, sometimes called the "turtle" should be on the bottom. The speedometer cable exits the passenger side and routs up the inside right of the firewall thru the gas tank channel to the dash speedometer. If its facing up it's wrong. During Model A production there were seven different speedometer gear caps used. The front mounting point for your rear radius rods should be down for the radius rods to fit, that should be your first clue.

    You're almost right Ray, but the proper way to do it is to remove the torque tube and swap it end for end.
