Three of these are used on each side at the back to hold the front of the rear leaf spring bracket to the body.

• Often these will be rust out & when you go to remove or change the bracket you find out the hard way.
• Supplied individually.. but a good idea to change all 6 if doing this job... once..!
• There is also a clip that looks like this ..used on body panel mounting.. a lighter duty clip.. often confused by some online commentary for this retainer.  
• These allow extensive thread through for correct bolt.. DON"T USE INCORRECT BOLTS.
