Has anyone tried one of these and booted the slip yoke? I'd just like to be able to loose my rear drive shaft and be able to limp home in FWD without loosing all the oil in my transfer case. It also seems that this would be a good option with a long slip yoke.

Yes, it will work.

Anybody know were I can get one without buying the whole sye kit?
If all else fails I'll make one I have a lathe and mill.

That's what I did.
Get the right seal and build your flange around it.
