Hi All
Brian,
I compared the page you sent and the tank on fleabay
I also looked up my own parts book which has the same diagram as yours
Theres a large cutaway portion on the parts book tank where the saddle nose fits
The ebay tank does NOT have this ???? ????
I phoned my friend with the ZB and he looked at his bike, the parts book pic and the ebay tank
Our conclusion is that it it wont fit with the normal saddle arrangement
Let the buyer beware!!!!
