Swingarm switch, looking for bearing sizes was created by lewisj
Replacing my 73 Z1 swingarm with a zrx 1200 swinger. Those builders that have made this switch, what swingarm shaft are you using and what are the new bearing sizes for correct fitment. Thanks in advance for any help!

Thanks TexasKZ! Tough to sort through all the builds and find exact measurements or diagrams, but this info really helps.
