You can put in an NP205 or even the Rockwell T221 if you find one. You will need the adapter and either lower your existing transfercase crossmember or get the correct one for the NP205. Sorry, don't know whether a Jeep or International one will be the same.

I don't know if the 69 K5's had the NP205. Most 69 pickups had the Rockwell T221.

What transmission do you have?

If it is a 4 speed manual, it will bolt right up if you get an adapter for the 4 speed and the NP205, NP205 it will bolt right up. You will need to either lower the transfer case crossmember 1/2" to 1" or get the crossmember that was with the NP205.

I can't speak on if it is an automatic - I assume you will be fine but I am not familar with the adapter differences so I will let someone else address this if it is an auto.
