Hello

Does anyone know if Ford used the same gear tooth profile for both tha early 32 and model a 4.11:1 gear set as the later 32 and onwards?

The reason for asking is that I'm building a rearend with mixed and matched parts with a carrier from a Chevrolet (yes I said it).

I could turn down a 34 ring gear I have, but it would be alot easier if the model a early 32 have the same tooth profile.

Best regards,
Magnus

The early model B axle is a lot like the model A axle. The pinion is a gear on the drive shaft. Ring and pinion are matched sets so I wouldn't recommend swapping different gears/shafts from different types of sets. It's easier to find good used stuff that will be known to work than mixing & matching things that are unknown. The 28 to 32 type axle is not a real strong unit but I guess it depends on what you want to do with it.

Find the tooth count for both and that will tell you a good bit. If they have the same count then it depends on the teeth. It could be a lot of work to find out it won't work. Why use a Chevy carrier? Using different axle shafts?
