You know some times it's cheaper to buy a complete box already built than try to rebuild one yourself. There is a several places on the net you can look for parts or a complete box already rebuild should you choose to go that way.
LMC,Brothers,The Truck & Car shop etc. may have what you need

PS. you might try a company out in Calif. called Obslete Parts or a Chevy Dealer dealing in new used parts there several who do that.
