The Rockwell 221 is a solid transfercase, but not as nice as sturdy as an NP205. For normal use, you shouldn't have a problem. If you're going to be doing some rock crawling, you may want to look for something else.

As far as I know, a 73 truck shouldn't have had a Rockwell. I should be either a NP205 or a NP203.

Many of the rockwell cases had PTO capabilities, so that is a plus if you're going to use the truck as a work truck.

A buddy of mine rebuilt the rockwell in his 66 3/4 ton. He found the kit on the web and found a parts case at the swap meet for $50.
