Where do people in the states get a M11 bar or bolt for a the counterweight? I can only get imperial stuff around here.
Try Aliexpress. That is where I (as a European) get all imperial stuff (like 3/8” or 1/4” screws) from.
M11 seems a bit strange though, in fact, I don’t know if that even exists. I know M10 and M12. In the AZ-GTI you will need M12. I know that, because I just bought a long M12-srew for my AZ-GTI.
