Well all bushings showed up by Monday A. M. springs went to rons driveline witj new bushings. as it turned out all the differant part number bushings were the same. In another word several sets of each with differant numbers but were same bushing. Added a leaf and replaced all u bolts. Truck looked level to me before and still does but looking at distance between spring bumper its up a little. Rides a little stiffer i guess. Noise is gone. The bushings looked bad to us when looking with a light but the guy who rebuilt springs said weren't all that bad!
