Early birfs still have only one groove but it is a different place to work with a shallower drive plate and with Aisin hubs without an additional groove. In addition if one uses AVM or Warn hubs no addition groove is needed with any birf.

Roger that. My mistake.
Actually, 1/1991-4/1994: 43405-60120 birfs are shorter. The snap ring groove is in the same place relative to birfield length.
As stated many times before:
1991-4/1994: 238.5mm
4/1994-EOP: 246.55mm (43405-60070)

Great intel. My point for community-knowledge was: Some early model 80 series' do not require replacing the birfs (or machining a snap ring groove) in order to run manual (Aisin) hubs. My apologies for getting the details incorrect.
True if you measure from the end
as you know the earlier drive plates are shallower for the overall shorter earlier birf.

Yes, I go by how Toyota does it which is to measure the length of the main assembly under discussion.

I would avoid AVM's like the plague. Their soft aluminum body and very thin steel bolts cause corrosion due to the aluminum or steel chemical reaction. This means when you go to remove the thin hub bolts they end up breaking off. I have had to use a BFH and chisel to cut the AVM hubs off (both sides) due to this.
I will only run Aisin hubs after that experience.

Friends dont friends run POS AVM hubs.
