KZ550 Sissy Bar

I have an Amco sissy bar (#93576) for a 1980-1981 Kawasaki KZ550. It is in its original packaging except for one of the legs which I removed to ensure the chrome is good (it is). In terms of fitment, there are two holes at the front end of the bracket. One is an oval hole (Call it hole A1, closest to the end), other is a round hole (Call it hole A2, about 1/4 inch away). Then there is the other main mounting hole down the bracket a bit(call it hole . Distance from center of hole A1 to center of hole B is 9 3/8 inches. Distance from center of hole A2 to center of hole B is 8 3/8 inches. Approx overall length is 20 inches long (looking at side of bike from front to back). Overall height is about 28 inches high. You can have it for my cost of $35.00 as it is just not going to work on my 1000. Thanks.
