This is a single new standard REAR leaf spring U-bolt. This will fit the rear axle tube and springs of the MB, GPW, CJ2A, CJ3A, M38, and CJ3B. This is too short for the M38A1 spring pack. The jeeps listed require four of these standard ones for mounting the rear axle to the springs.
Measurements: 7″ from top inside to bottom of leg. 3″ respectively across inside. 2 1/2″ of thread.
