These rod linkages are intended for "universal purposes." When using linkage to connect your floor shifter to your transmission, ensure both the shifter and transmission are in the same gear position.
The 5/16" rod linkage comes with ball joints on each end. Use of left-hand and right-hand threads makes adjustment simple by spinning rod to lengthen or shorten when installed. Two jam nuts per end are included to tighten linkage as well.
