Now I should be able to take the HD dif, output shaft, and the tail housing from my current tranny or with the 4th gear sheared not a good idea?

Swapping the part will be just fine as long as they are in good condition, so make sure you inspect the differential good before installing it into another trans. It would also be a good idea to clean the parts off to get the debris off of them as there will likely be a small amount of normal debris attracted to the parts.
