SHS 6mm Steel Bushings

Too thick for my JG gearbox that I'm working on, from what I'm reading online this is a common issue with these. So beware that you will likely need to either sand, file or otherwise remove material to be able to shim a mechbox using these. Other boxes might vary but I've found allot of threads on forums with the exact same issue I'm facing. Otherwise quality is good just a PITA to get everything to fit.
