This steel clevis has 5/16-24 female threads to fit standard Tilton, Lockheed, and Girling master cylinder pushrods. The 5/16" diameter cross pin is retained by a captive quick-release spring clip.* The slot is 5/16" wide and approximately 9/16" from the center of the pin to the base of the slot (1 1/4" from the pin to the end of the clevis). 5/8" wide overall.
* Wrapping the spring clip with a single wrap of safety wire will result in a more secure installation, if desired.
