So eventually I am going to have to replace the training arm rear attatchment. Pipe pivot is what I think it called. This looks not fun. I am thinking I need Yamaha rivets, and a pnumatic rivet gun. Is that a correct thought? Any suugestions on a manufacturer for the gun. I do not need the gold plated one, but I would like it not to be a single serving either. and how evil of a task is this? looks like the lower panel must come off. Then drill out the old. Pop in the new. Anything to be aware of? Thanks
