Hi Paul, I've had good luck for hard-to-find Ford parts with a company in Ohio. They are Green Sales, 2172 Seymour Avenue, Cincinnati, OH 45237. Phone number (I hope it's still good) was 513-731-3304. If you have a part number that will help, but if not they can usually look it up for you. Good luck, Nick Brann - K.C., MO

Paul. You might try advertising for a 17 tooth gear for the ’56 cable in the classifieds. There may be some readers that are overlooking this thread.

Paul........I know that would be a rare factory setup,but they did offer it as an option.The parts manual shows a 17 tooth gear for it. For most uses,the 3.23 gear and straight transmission is not a very good combination,but it is working well for me.

Paul: unfortunately this won't help you.. it's unlikely that Ford ever supplied O.D. transmission cars with a 3.23 axle. That gearing is very high for that application, so finding that speedo gear isn't likely an option.

I've already figured out what I need to correct the speedometer.All I need is a 17 tooth gear which is what Ford would have used in a car with a 3 speed or OD transmission and a 3.23 rear gear,which is what I have.Only problem is that they are scarce as hen's teeth.Evidently very few 56 Fords were ordered with straight transmissions and 3.23 gears.I'll just have to live with a 20% speedometer error.

[quote][b]The Master Cylinder (5/19/2011) Did Ford actually have two different Speedometers in ’55, one for the Car and one for the T-Bird or did they just change the face.
Not sure, but my '55 chassis parts catalog lists different speedo ass'y & dial face part#s (does anyone know if NOS speedos come with a dial face?). I assume your speedo became optimistic after installing the 150 mph dial face? If the % change mirrors the speedo error reported in all the '55 T-Bird car magazine road tests, then it's possible the speedo mechanisms were the same.
Sorry, didn't mean to hijack thread, just curious if anyone knew... My speedo was off anyway because I have a C-4 and 3:55's. Someday I am going to order a ratio adaptor http://flat-o.com/accessories/speedcable.htm from Flat-o, already have the two piece cable. Gene assures me we can get it close. Right now I just use my Tach.

Folks the answer is what was the ratio of the rear end in the car the st/od was removed from. the speedometer gearing in the transmission was obviously set up for that. To correct the speedometer you need to determine the speedometer error, a gps is great for this. Then apply this percentage to the tooth count to get the correct new gear. be aware the drive gear on the transmission output shaft may need to be changed due to compatability issues. I think you,re on right track with rear end thought, cant be exact but generally our cars are something like rear end ratios , Std 3 speed 3;7, O/D 2;89, FOM 3;2. so either way theres a difference that mixing trans with the rear ends will result in speedo error. At least thats how i see it.
