I bought the leaf springs, the shackles, the 5 hole plates, the U-bolts and nuts,cost about $390.00. Then I bought my shocks from
Pete and Jakes. http://www.peteandjakes.com/
Also from P&J I got shock studs and shock mounts. They cater to F$%* cars and trucks but the products are high quality and some will fit our trucks. Oh, and I fabbed my upper shock mount using a 2" pipe. http://good-times.webshots.com/photo/2405234580099708909IEzOyh
