Drive train question

[bails85]

ok so i had an aw4 with a 242 transfer case in my 89 xj. it went out and i got a aw4 with a 231. my question is what do i do about the vaccum disco part. the 242 didnt have a vac disco but the 231 came out of a rig that did have the disco. my front axle is a hp 30 with non disco. i do plan on putting a sye on it. the sye comes with its own housing so im just curious to know if i am going to run into any issues. thanks for any advice.
