seal question--getting rid of vac disco

[MWinland]

I've seen so many different seal numbers, and I don't know what's correct. To eliminate the vac disco and upgrade to a 1 piece shaft, what seals do I need?

The Mad XJ write up is just for the 297X disconnect shaft swap, not for the disco delete swap.

 

I just stuck a 1 piece axle shaft in my YJ and you need to pull the diff out and put a seal (national part #471763) where a non disconnect seal would normally be (its not machined to use a regular seal). the seal in the disco housing won't be needed anymore but i just left it there as a dam to maybe keep mud from filling up the disco housing.
