Yes, the original Sure Grip design was the Dana Power Lock. Many parts interchange with the Power Lock for the Dana 44. This is the clutch type with the 2 cross shafts.


Put Mopar side gears in my Chevy positraction unit so I could swap in larger fine spline axles. Side gears were from 65 and later as I recall.
