I bought a 1999 Sugar Sand Heat jet boat and I believe it is on a Shorelandr trailer.The ID number has faded away on the frame of the trailer. I need new u bolts for the leaf springs and Shorelandr can not help me with out that number to look up the part.If someone has a Sugar Sand sitting on Shorelandr trailer and you can read the ID number let me know.The u bolts are 1 3/4" inside by 2" high by 3/8" maybe 5/16".They are almost rusted through.Thanks, Steve.
