    JTS 300M Wrist Pins @ AJPE

    AJPE stocks several sizes of 300M pins from JTS
    aka JT Stewart
    aka Dynamic Machine

    Sizes:
    1.094 x 3.400, 3.250, 3.125"
    1.156 x 3.300, 3.400"
    .990 x 2.930 + 3.125"

    They are a little expensive,
    & not lite wt,
    but like everything from JTS,
    they are the best, & worth it.

    The only wrist pins we use + sell.

    Chris @ AJPE
