Default A/B diff swap

Hi Gents,
I want to put a faster diff in my 28 Roadster Pickup.
Are the rear axles of all the Model As the same dimensions and can I use a B rear end and up to what year?
Regards
Chris

early 32 same internals, There are a number of ring & pinnion ratios avalible , or you can fit a Qickchange & have any final ratio you want . Mitchell over drive works well. plus some 4---5 speeds ,

The spring on the B rear end mounts behind the axle. Just get the right gears for the A rear end. As noted in the previous the 1932 (except very late) gears are the same as a Model A and can be used.
