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.
