That's what I was thinking, groove the bushing, drill and tap it for the greas fitting, drill a hole to fit it, and have the bushing and grease fitting screw together and 'sandwich' the steel of the swingarm.On a less intensive path, couldn't you just make urethane bushing instead of bronze? Gotta be easier to shape and less play but not none, doesn't transmit all the stress to the swingarm. Of course, they need to be lubed too or they stick and squeak. Rubber is more forgiving.Scott
My estimation would be that if they are plastic, they are already something like polyurethane, and I doubt that any real improvement would be found with bronze.It might just be best to leave them as they are.

Any other way of reducing side ways or X movement of swing arm?
Tom , I recently sorted a 55 frame out for another british bullatier (dan ford), the frame was old and the paint was tired after having it chemicly cleaned , you can see all the braizing on it?I then got it proffesdsionally painted for himthe earlier UK bikes used a bronze bush settup at the back with pleanty of grease nipples , I replaced the shaft as it was a bit "dull" , what a nice setup!enfield thought proper in those days , the outer large nuts were made in such a way that a screw was placed in the frame and locked the nuts , the quality of the frame inc the headstock , made the indian frame look like a "photocopy" read from a distance ,,,
