I am in need of a new spool (the part that holds the line) for Craftsman Weed Wacker model # 257.799760 (electric). I've already checked with searspartsdirect, and it's not available any longer. Maybe someone out there has one they are willing to sell???? I think I can fashion a couple of doughnuts out of foam (after the spool is hand-wound, they go over the line at the top & bottom of the spool) - but maybe they might be available, too?? Hope someone out there is able to help me.
