Default Re: gear ratio

What 42Merc says , is probably the easiest and best way to achieve your goal. I think that the 49-51 Ford had a drop out center , If you can find a used rear diff, or just the drop out center from one of these that was originally an automatic car, I believe the rear ratio was 3:31. If I am wrong about the 49-51 Fords having the drop out, I know the 52-53 Fords did, as I have changed many center sections on those. The whole Diff may be able to be swapped in, but you would have to measure to be sure. I have not worked on one of these early Fords for over 30 years, and none around here to look at and check for you. good luck.---Jim
