    Hi, I have a 39 chevy sedan and it is missing the arms that go from the wiper tower mechanisms to the vacuum motor. Was wondering if anyone has the measurement of both the arms? Thanks in advance.

    Here you go: Long arm measures 18 7/16 total length, 17 7/16 center to center of shaft holes. Short arm measures 6" total bent length (5 7/8" measured length end to end with bends made) but must be bent up 1/2" from level on one side - so the measurements are: from wiper motor: 3 7/8 parallel to surface, bend up by 1/2" (measured length of rod to bend is 7/8" from break point to break point, and remaining (parallel to surface) length is 1 1/4"
    wiper motor holes measure 1/4" and are drilled 1/4" from center of hole to edge, wiper transmission (chrome post) is 1/8" hole and again drilled 1/4" from end. Rod material width is 7/16" and 1/8" thick
