    The FIRST item I bought for the bike, was this excellent gage, to evaluate/reassure a sound bottom end, my budget was snug.
    Fit & has worked perfectly....
    Almost...

    There is a heli-coil in the aluminum tube.
    NP, I have M8, 5/16”-18 heli’s on hand...
    But, the thread verification confirmed neither was correct... roh-roe

    Call or email Fred (Eaton) at OldBritts. They are great people and I'm sure he will be able to tell you the thread pattern (or maybe even be able to send you a slightly shortened section).
