    Rated 5 out of 5 by from Great parts! This was the first purchase with Jegs and everything was great!

    Rated 2 out of 5 by from Bad quality control I received this master cylinder for my restoration, the cap was split due to stamping failure, they did send me another cap that was not split but, had screw driver scratches from removing clamp and poorly defined, crooked stamped lettering, it was clearly another cap that didn't pass QC.
