Rebush. Drill out the originals (3/16" bit, I believe, but check first) and lightly chamfer the empty holes top & bottom. Cut (or rather, tear) a dozen or so short pies of bushing cloth of the correct width. Clamp the rail to the bench and run all the strips through and cut them all at once. This goes pretty quickly. Do NOT use any glue – the chamfering will hold the cloth in place quite securely. After all the holes are bushed insert #7 bridge pins and size overnight with your favorite sizing agent (I use isopropyl alcohol, but profelt also works fine). This typically leaves the bushing ready to go, with no further easing required.
