David: I can repair your pedals using acetylene welding equipment which I have being a former auto mechanic. I have repaired many like yours, and if you don't mind sending them to the Chicago area, I'd be happy to do the needed work, very reasonably. Otherwise, find a local welder, it should be no problem for an experienced person. Mike Kurta, RPT Chicago chapter
