f ing criminals. 400 to swap a balancer, that robbery.

id keep looking, hell maybe bring your air gun, and ask to use their air line. pretty sure wheel turned you can get a gun on the bolt and break it free. just leave the splash shield off.

you had not said how large your air tank is, i got a feeling its to small for the gun to work at its max power. a real compressor should get the job done.
