Hi Moses
here are some pics of the 1966 Aussie Willys 4WD Pickup steering box not sure of the brand but it sure needs some seals it all looks original i would not expect it to be a modification
i would expect the seals to be same for rhd & i hope that most internal parts will interchange between left & right hand drive but apart from the leaks it seems ok
i know there is a lot of play in the steering arm on the lower swivel hub bearing i will have to investigate this issue it may just be loose bolts
cheers ian
