This kit was for a repair (bolt fell out). I was hoping to have a diagram of the saddle with the various fastener pieces (i.e. the star washers) to see if anything was missing. If missing a part from the "stack", that would require a partial disassembly of the saddle, and placing new parts to replace the lost ones. Unfortunately, nothing was provided, nor could I find anything on-line to assist. I replaced the bolt using the tool provided (yes, it really is needed to be made like that) and have no known issues.
