OT. I see they had a 3.90 carrier complete listed. That is what I have for a spare out of a 1952 DeSoto. Didn't see it listed but they may have the heavy outer seal. I was lucky enough to get National 5797. If you look back Averyman found a heavy seal that he had to make some alteration to use.

   Marc... would you know if there is there anyone up around your way that might have a set of spider gears & the case for sale for the woody. I think it's called a "loaded case".

If it is just the carrier that you need you can use one from an early 50's model Dodge or Plymouth car. Pickups too I think. Apparently the correct ratio is 4.11 to 1. I just found one that is 3.9 to 1 and I plan to use it. Later models had a finer axle spline pattern that was not compatable with the narrow guage axles. You have to pull the axles back to get the carrier out so you can tell right away if it is the right one. The ratio is usually stamped on the outer edge of the pinion gear. All above info is from Ted our local bombardier pro. For those of you with early wide guages you could use the auto axles or likely the whole assembly. Since you'd be installing it upside down you'd have to weld the vent hole up and tap in a new one on the other side.

  Cranman if the correct ratio is 4.11, which is in the woody, & the correct ratio is 4.89 which is in the narrow metal, can I switch the whole insides of the case from one to another ?? I guess the axle spline has to be the same & I will have to reuse my own axles.

I never heard of a 4.89 in an early dodge ?? that would be compatable with your axles. My 3.9 spare out of a 52 Desoto has the course spline. If you are talking about the 4.89 Dana in the later model metals, I don't think the axles would work. I think it is a totally different set up. Going from 4.1 to 3.9 for me will be ok and may even be better for gas mileage. Won't make much difference either way I suppose. At my age a little howling doesn't matter much, getting deaf so I may never have to use my spare but if I don't keep it in the shed , sure as hell I'll need it.

   Cranman I have to look at an old 50-51 Fargo pickup when the snow goes here. There may be a diff in it. Can you tell me if the rear end in a 1949 Dodge power wagon would have the setup I'm looking for ?

    Thanks for the advise Marc. I will check it out. I was talking to a machine shop this morning & they say I can get a diff from a GM truck & have it narrowed for a reasonable price ( similur to Swamp Dawgs ) If I went this way I shouldn't have much trouble finding parts if need be. Marc all my pics are on here in the wooden bombardier section. I'm talking about a diff like the one on top in the top pic. It is a Dana 44 & came from a narrow gauge metal. It is 4" too wide. He says it is pretty straight forward. I'm thinking when he cuts the outer end off the axle he could weld back a piece of 3/8- 7/16" plate drilled out to accept my sprockets. Sound about right ????????????

  Cranman here are a couple of pics of a diff that is supposed to belong to a 59 Dodge. It's three & a half hrs. east of me so I'll have to get a someone to size it up before I go there.
    Let know what you think. It looks close to mine. If it's the same spline & bolt pattern... it should be good. Do you know what the ratio would be in a 1959 ??

Well it looks a bit like it but I never seen one with those bolt holes tapped in at the spline end. They might be ok for a brake mount. I suppose you'll have to get someone to pull the axles and send a pic of the spline. If it is after 1953 or so it likely has the finer axle spline and therefor of no use to you. AS to the ratio it is hard to say, you'd have to turn and count or take it out and look at the stamp.

The diff I just removed has the same tapped holes.  It has a 30 count splined axle.

  I have another question for someone to answer. I was told today that he has a couple of aluminum sprockets taken of a metal bomber.
   I can only imagine that owner lost his diff & installed a woody diff & sprockets. If I am right I may have parts for my diff. Is there any way that the diff from a woody will fit on a metal bomber & have the sprockets line up with the wheels ??

                                                                           OT ??? ???

  I'm looking for the # of the seal that the hub fits into. The pic below shows what I am talking about. We are having trouble matching one up.
