Some information on 1928 Dodge Fours.

I don’t think there’s a direct modern replacement to the original felt inner seals (two felt seals inside pressed steel housings).  
 

I turned up a couple of adaptors in aluminium which sit inside the original steel housings but take a modern neoprene seal.  I can’t find the seal part numbers but according to my notes they were 1.43 x 2.06 x 0.31.

 

as Matt said, the outer seals also need the housing (and hub) to be machined if you want to use modern seals - mine were 1.975 x 3 x 0.375.

 

if you do go with modern inner seals you probably need to add a breather.

 

cheers

The outer seal came in yesterday and I’m going to machine the outer bearing carrier today to make it fit. 
outer seal I’m using is F6252 -33-72-10 this one needs the carrier to be machined. 

Inner seal I used but a bit tight is 

1.437- 2.327. I like the sound of Rich’s idea better. 
Thanks for reminding me about the breather to Rich I forgot all about doing that. Where did you run yours from?

I just added a 1/8 hole to one of the rear cover bolts - top right (viewed from rear) I think.  That’s what Bob recommended - I thought it may get a little oil seepage and if it did I was going to add a tube but hasn’t seen a drop

Actually I used a 4mm hole (to allow a small tube to be soldered inside if needed).

Perfect thanks mate.
