Bolt and washer came out of end of shaft of the Kawaski fx691v and was lost. I live in the sticks and no dealer within 100 miles. I need to know the size of the bolt that goes in the shaft end. Clutch fell off but I found the key and spacer. I'm sure the bolt must be metric. I may be able to find one in hardware store. I'm old school and no nothing about metric.
