Do a search, many discussions here. Why not rebuild the original with a shortened arm and teflon links??

Well, I am glad to hear this about the conversions, I was thinking seriously about one..
So, regarding the original 2 tooth boxes, I heard of a couple complaints regarding the needle bearings.. Is it best to install and properly fit a new bushing ?
YES, a new bushing will be fine.
I've used the thin O-ring and thin steel washer that comes with some steering kits to seal the pitman arm shaft and it's worked fine. It just slips on the shaft before you bolt the box to the frame.
