The Bottom Case bolts from a yamaha fit. The actual bolt size and the socket used do not match up if you go to a bolt section of a hardware store. The head is smaller than what would normally be. 14mm Socket is used if not mistaken where as if you go find a bolt with the same threads size and diameter it will have take a 15mm socket. Hit up Jetmaniac for a bolt kid. Also, I think when you got that pipe it had 2 long and 1 short that were from a Yamaha
