NP 203 questions - The 1947 - Present Chevrolet & GMC Truck Message Board Network

This last weekend, I bought an 83 that was originally a C20, but has been converted to 4wheel and has a 6in spring lift.

It currently has a 400 with th350 and np203. It also has manual lockers in the front.

When I have the shift selector for the transfer case all the way forward, the truck is in 2wheel, with the front drive shaft turning freely by hand. This is not at all like the shift pattern I am aware of for the 203.

What am I missing?

Thanks in advance for your help.
