This is a new very correct and high quality pair of spring bolt hangers or mounts. These are usually badly worn from a worn out spring bolt moving around.  These are heavy duty correct replacements.   These are 1 7/8" inside measurement. Normally the main spring with the bushing is 1 3/4" so you need just a little more room to actually install the spring eye end. When you tighten it down you will be glad you had a little extra room.  These will fit the MB, GPW, CJ2A, CJ3A, and CJ3B.  These jeeps take four of these brackets but these are sold in pairs.
