I'm sure I saw a post on here once telling me this is possible, something about dana200 parts in a 205 case? anyone know how its done please?

Try a search with NP 200, not Dana 200

ok yeah I did that actually, ended up with a lot of stuff I didn't need, I found the original post and it indicates np200 parts can be used but I am looking for specifics on this setup, do you need all the 200 internals? does it just bolt in? is machining needed? ect
