NP205 transfer case rebuild. The NP205 came from a 1978 F-250, the 1976 came with a full-time NP203 – the 205 is much better…

And last but not least, new driveshafts.

Custom-built front and rear driveshafts freshly painted. The original driveshafts were the wrong length, badly rusted, and not even close to straight. The intermediate driveshaft came from the NP205 truck so it was the correct length and could be used. |
