    '66 power antenna bracket bolt thread size

    Anyone know the thread size of the 2 original bolts that hold the power antenna bracket to the plate with the weld nuts? I had to drill out the broken bolts and want to tap the correct size back into the weld nuts.

    Rob -- pulled the top P.Ant mount bracket bolt off my '65 for this pic (was working in the general area anyway). It's a 1/4" diameter (7/16 indented head bolt) with a captive lock washer. Overall length is 0.915", and you can count the threads [which are 28 threads/inch pattern].

      Wayne,

      Thanks a lot, I appreciate it. I'll get a tap and rethread the weld nuts on my bracket. Thanks again...

        Richard Fortier is reproducing those bolts now - he showed me some from the first run off the tools yesterday at our Michigan Chapter Meet.
