By now I could use some serviceable used parts in usable condition that have just worn out since I bought my bike new in '75. I can replace some of these things new, but other things I wouldn't mind having if I could find decent used stuff. I don't know if this is the right place for this sort of request, but I could use a decent seat, center stand, right side muffler, instrument cluster, handlebars, and rear fender. I ride my r/60/6 daily back and forth to work (100 miles). It's always been a good runner. 'Rusty but trusty, I've always rather ride than to primp, but it would be nice to replace the above...thanks!
