Rich, I think I can help you install your locker, if you want to give it a try.  You will need a shim kit for your dana 35.  You should be able to pick one up online for cheap.  Talk to Pete for more info.  Also, we will need:
Locktite
Rollerbearing grease
Diff fluid
New bearings and races if your locker doesn't have them installed already.  Again, Pete can help you get the right parts, I imagine.  Also, if you ask him, he probably won't mind if we call him if we get stuck.
I learned a lot working with Pete on my locker.  Well, I watched for the most part, but I learned none the less.  I don't charge much, just beer, but I don't warranty like Pete!  Let me know if you are interested.
