Hey, I'm looking to replace my broken off fuel tank cover. I have an 89' that had the blue cover. I found this part # 51049-3711-8Z on the interweb and wondering if anybody knows if this is correct. This part# does not come up when I look up the number through Kawasaki. The P/N that comes up is 51049-3711-TA

TIA
