Model A rear gearing questions...

[John Kennedy]

Hey all, I just inherited two really clean complete A rear diffs. One seems to be 3.75 ratio, other seems to be 3.50 ratio if I measured accurately. Are these just average? Not sure what I want to do with them, already have a '48 truck rear for my A Sedan.
They have the stock brakes on them.
Thanks, John

3.78 is the normal ratio. 3.54 is the so called high speed ratio.

Good to know. I'll have to recheck the one then, it might be 3.54. Of the two, that's the "nicer" one.

The 3.54 is a keeper. You can get a better highway speed. I not a 100% but the lasalle gears give a better 1st gear & the 3.54s with a taller tire gives better highway. Correct me if I'm wrong.

I'll probably verify ratio, and list it in the classifieds. Too nice to become "yard art"
