Technical Ford banjo Axle shafts

I've been looking around and I've found measurements for the whole banjo rear but not any specs for just the shafts themselves. I'm looking for year brackets, tooth count, length and anything else that makes them different form each other. '28-'48 cars/trucks.

So far I have:
'35 car rear @ 16 tooth and a total length of about 33"
'46 1/2T truck @ 16 tooth and a total length of about (I'll check tomorrow)

 

Early Ford axles, latest to early:

P***enger car 42-48, Pickup 42-47
21A-4235 16-tooth gear 33.70" overall length.

P***enger car 39-41, Pickup 39-41
81A-4235 16-tooth gear 32.85" overall length

P***enger car 35-38, Pickup 35-38
48-4235 18-tooth gear 32.85" overall length

P***enger car 32-34, Pickup 32-34


Your 28-48 P***enger and 28-47 Commercial Ford Parts Manual (The Green Book) is your friend.

 

If you are interested in identifying Olde Ford parts and comparing specs, not owning the parts book is crazy. You really need the '28-48, and it's good to also have the specific year one for your car. The book is not a luxury...

 

Thanks for the info, now I have to find the book or cd.

 

It is tremendously useful in figuring out what's out there, what might fit what, etc.

 

1928-1948 Ford Ch***is Parts Manuals were produced year by year and then in several years together volumes. The last one was the Green Book.

 

Hmm, so I noticed that the '35 rear should be 18 tooth. The one I have has 16 tooth and 11 tooth spiders. So it looks like I can use them as spares also.

 

The actual case the spiders live in is the same, so you can use either type of spider gears in any center section as long as you get all the matching parts.
The catalog info is VERY handy when you are searching the fleamarkets...you go in armed with the dimensions, and part numbers that might be marked, tooth counts, etc. and ask the vendor "what year does that fit?." If he has no idea and you do...you've got a big bargaining advantage.
