THIS WAS A GREAT PURCHASE, THE ONLY ISSUE IS SOME OF THE HOLES DID NOT LINE UP HAD TO JIGGLE THE PIECES TO GET THE SCREWS IN. SOME WERE VERY TIGHT TO GET IN, MOST WERE EASY TO LINE UP. THE TIP TO NIGHT TIGHTEN EACH ONE YOU INSTALL IS GREAT UNTIL YOU GET ALL THE BOLTS IN A PIECE THAN TIGHTEN THEM ALL AT THE SAME TIME. GREAT TIP.
