Note this is only on the big (13") wheel Mokes. the small wheelers had Mini arms.

Murr sent me an email pointing out that the Moke radius arms were different than those used on the Mini and DID have two needle bearings.  See the parts listing in the link below.  Thanks Murr!

Thanks, Spank. I'll be ordering the extra roller bearing for each side.

My Oz Moke trailing arms arrived to me with needle / roller bearings at both ends and not bushings. Dont' know if that's "normal' but is what I had and I just replaced them the same way. I happened to have extra complete sets so I just stole the bearings from the second set I had

FWIW, On the more familiar bearing/bushing setup, I've had good success with just replacing the needle rollers and the shaft and leaving the old bushing alone. I've found the bushing doesn't wear and it is the bearing side that ceases to roll and just saws into the pivot shaft doubling the perceived wear/play.

Apologies. I am using the words roller bearing when in fact they are needle bearings. My radius arms are equipped with needle bearings at both ends. Was this a standard fitting at any time?

Two roller bearings is not a factory design.  The roller bearing and bushing have different outside diameters.  You have a couple of options.
1) order a second roller bearing and replace both needle bearings with your existing arms.
2) order new radius arms that have not been modified.

I suppose a third option would be to have custom bushings made to replace the needle bearing on one end.

I'm rebuilding the rear radius arms on a 1978 Oz Moke with 13" wheels. The repair kits come with one roller bearing and one bronze bush (that has to be reamed to size). My arms have two roller bearings on each arm. Do I just order a second roller bearing for each arm? Are they the same size as the bronze bush?
