not sure how the 4wheeling scene is in your area, but often front 3rd members can be found b/c people do a solid axle swap and they are just left over. E.g. nothing wrong with them, but they are functionally useless to the owner.

You should be able to get an open front 3rd for $200 w/o too much trouble.
Worst case, Car-part.com, searching the whole country, have a yard ship it to you.
And, yes, even if it comes from a vehicle w/ the ADD system, although technically it is a slightly different casing and axle, that can be "fixed" to work for non-ADD axles for the price of a hose clamp and 5 minutes of work.
