ANYONE KNOW WHAT SIZE ARE THE U-BOLTS ON THE REAR AXLE OF A 2004 F-150 4x4?

 

This is the size of the new ones I used to lower.... 7inches long, 3 1/4 inches wide on the inside, 1/2 inch diameter with rolled threads. The threads measured 9/16,(bigger because they are rolled), They came from Davenport Spring Co., Davenport, Ia.
Cost to me at Ford dealership $50.00 per set of 4. Hope this will help. JT
