I think the shape of the inside of the stock bushing allows for grease
to be retained inside. A delrin type sleeve replacement should work fine
but might need more frequent lubrication. The plain sleeve replacement
might last long enough for our purposes with just initial lubrication.
Give it a try. A lip on one end and clamp on the other sounds easy enough.
