As usual, as soon as I order parts for a bike I find one more thing that I need after I get it! It appears to be a missing push pin based on what is on the left side: does someone have a part#? I looked at the diagram and cannot figure it out. Also, is there a place I can easily get one from? I could order it but I know the shipping will probably cost 10 times more than the part! Thanks in advance...Bob Z.
