Hmm, not sure what the early style looks like, but I think there's a short stub out from the dif with a bolt on ring or something like that. Axles are two-piece. One solution would be to swap to late style axles. I would contact Devin at Unitrax or just post the question. I looked at an old post of mine and found this:

I believe the early style axle is on '32 VIN numbers thru F257904 and the later style is from F257905 forward.

I must have researched it at one point, but I can't guarantee that info is correct. You'll need to do a little digging. Maybe post a pic of your axles going into the dif on the forum and ask.
