Chilton's says the Jeepster Commandos had Dana 27AF's from '66-'69.
'70-'73 Commandos had closed knuckle Dana 30 axles. There was also an open knuckle Dana 30, used on the '70-'73 Wagoneer, and the '84-'86 Wagoneers Cherokees and Comanches.
According to Standard Catalog of 4x4's, all Jeepster Commando's, ('67-'71), came with Dana 27 front axles. Commandos, ('72-'73), came with Dana 30's. Cj's from '56-'69 had Dana 25 fronts, Dana 27 from '70-'71 and Dana 30 from '72 on. I believe all the Dana 30's were open knuckle while all previous models were closed.
I have no first-hand knowledge on the subject, I'm just repeating what's in the Chilton repair manual for "Jeep Wagoneer / Commando / Cherokee / Truck 1957-86. Please don't get the impression that I know what I'm talking about .
