4x4 front end, brake question

What is the first year for open knuckle - disk brake front ends?

67-68 were closed - drum

69-70 ? (did they make an open knuckle - drum)?

71-72 were open - disk

All axles would be Dana 44's (I assume)

It is my understanding the the closed knuckle drums were 67 thru early 69. Then they went to open knuckle with drum for late 69 & 70. Then 71 and on is open w/ disk.

Hit it right on the mark---

AND on the 3/4 tons 71 was the year that they went to 9/16'' wheel studs
