NP205 transfercase and transmission

See here's my problem a NP205 transfercase fell into my hands with 4 speed transmission with granny gear. The transfercase is cast iron with gears instead of a chain and is lowed geared. Basically you can put the vehicle in drive let it idle and you will creep along either moving or pulling any thing with in reason. And I need to sell it! It came out of a project 4x4 3/4 ton chevy, the transfercase and trans seem to have been rebuilt. I am asking $1500
