Does anyone sell parts for the Bally drop target units ? My Captain Fantastic is fantastically worn out in this department. Lots of slop in the linkage. Targets randomly stay down. New targets, tightened springs, no change. Tons of slop in the pivot points from the coil on out. The outside reset arms are sloppy. There were over 150k pins made by Bally between 1975 and 1980, and most of them have drop targets. Really surprised there isn't a rebuild kit for this high wear item.
