I am looking for some one who could change out the 3.25 that was installed in my 39 rear by the po to a 3.78 or 4.11. Prefer some one who is in surrounding area to Columbus Ohio like 4hour trip and knows their stuff. Probably going to a 5 speed behind my FH. Thanks, John

I had a /36 half-ton very original including faded Ford green. Bought it w/a 4.11 soon purchased a 3.78 by cross-country phone call. Upon arrival, install. Perfect for town roads and in-town in second to third.
You would not enjoy a 4.11 = made for loaded pickups, high rev @ 50mph+
thank you -

Maybe you can find some to swap you a ready to go 3.78 rear for yours.

Thinking about the 5 speed and the 29 inch tire is why the 4.11 thought along with the built flathead that is currently in the car. The complete swap would be OK if I could find a good one.

I had a T5 in my '36 coupe with a built 59 A and the 3.78 was perfect.It had a 57, 9" so gear change was easy.I at first tried a 3.90 and that was to low.My 1st gear on my T5 was a 4.86 and 5th was .76. I could almost start out in 2nd gear.
