OK, now lets talk about the problem with the holes in your rails. Seems to me that at one point in time, the rails had broken off rail bolts, and instead of drilling out the shank of the broken off bolts, removing the cloth and cushions to remove the floating nut plates to repair the rails...SOMEONE got the bright idea to drill out the floating nut plates from the topside of the rails, destroying the set of rails
