Had to make clutch head screwdriver out of and old chinese common screw driver (flathead). Apparently O'Rielys NAPA and Harbor freight employees don't know what a clutch head driver is. Napa said I could order a set of 100 screw drivers and that had 2 clutch heads in the set. 5 minutes with a grinder and bam! got myself a new clutch head, made removing the clutch head screws that held in the return spring for the horn easy and without any damage to anything (other than that cheap screw driver witch in my opinion is much a much better tool now).
