Need 2 rear spring u bolts

this is the style that goes down from the top , nuts are below leaf under heavy plate

FYI - those are spring clips. There were three different lengths and two designs for each length. It looks like the nut in the picture is the 7/8" tall nut. So, my guess (from looking at your photo) is that you are looking for the 7-5/8" long clips???
