203 was a chain drive case, 205 was the cast iron gear drive case.
In this post there are a few good pics of the 205 and 203 side by side:

There is no seal kit, just individual seals and a gasket set.

If the transfer case is the original, it's not a New Process anything.

1959/72 F100/250 4WD's came with Spicer-Dana transfer cases.

The NP203 & NP205 transfer cases were introduced in 1973.

1967/72 F250: Spicer-Dana Model 300683-3 Transfer Case-GEAR Driven.

1967/72 F250: On the side of the transfer case is a metal plate with this Ford ID number stamped on it: C7TA-7A195-D
