This Ford C-4 driveshaft slip yoke measures 6.5" from the center of the U-joint cup to the front end of the yoke. Fits transmissions with 28 spline tailshafts. Accepts 1310 style U-joints (popular Chevy) with 1-1/16" cups and a spread of 3-7/32".
Note: Due to the length of the yoke, it will fit C4 transmissions ONLY, and is not recommended for use on an AOD transmission. The expressed measurement or length of the slip yoke is taken from the center of the u-joint to tip, not overall.
