Okay, I'm sure this has been asked a bunch of times before, But google is failing me atm..
So i want to throw a locker in my front axle, Figured while i was in there i'd upgrade the two peice vacuum disconnect shaft to a one peice..
And while i'm at that, I might as well swap both to the later model bigger ujoint shafts.
Thats where I'm stuck, What years came with the larger ujoint shafts? I heard you have to use a different seal then stock for the one peice shaft? If anyone could link me to a good write up, That would be great.
