1967-1969 K series trucks used the closed knuckle Dana 44 with drum brakes.

1970 K series trucks switched to the open knuckle Dana 44 with drum brakes.

1971-1972 K series trucks had the open knuckle Dana 44 with disk brakes.

It has been my observation that the manual shift 1967-1969 K10's and K20 had the Rockwell T221 transfer case while the 1969 K5 would have had the NP205 or Dana 20 transfer case. I believe the Dana 20 was never offered in any K10 or K20, just K5's.

I also believe the SM420 was used in the 1967 trucks but from 1968 to 1972 the SM465 was the manual option.
