I have a 46 CJ2A - There are 10 leaf springs and 1 rebound spring in the rear pack. The U bolts are 3" centers and measure 6", inside of the U to the tip of the threads. The U bolts appear to be to short, very little of the long nuts were catching the threads. Can you tell me what U bolt part number would work for my situation?
Willys Jeep Parts Tech:
These will have an overall length tip to tail of 7.25" so you should be all set with them. Email mike@kaiserwillys.com and we can help. Thanks!
