I have a 2003 Kawasaki Bayou 250... I installed the shoes and tried putting the drum back on and it wouldn't fit. I had the adjustment lever wing nut taken off and the lever was back and the rod the pushes the shoes was at the flattest position and the drum still didn't fit. The drum was catching on the brake shoe material. I held the old and new shoes side by side and they were slightly different size. What I had to end up doing was grind some of the sleeve on the flat part of the show to get the assembly small enough to get the drum on... It was a pita... These are a great value but the specs must be off a bit in China....
