Gear shifter seal driving me crazy !!!!!!

[tjakes680]

I have a 2003 Kawasaki Lakota KEF 300 sport It has a leak on shifter shaft I got a seal from ebay put it in and still leaking . So now I ordered one from Partzilla a OEM seal here is my problem on the blue print of the gear shifter shaft it show what looks like a seal but its called a collar Then on the engine cover diagram it shows a bushing and a seal so I called Partzilla they said get the bushing and seal and no one can tell me what the collar is or if I need it I also have the service manual and cant seem to find anything on it as well does anyone know what I need a bushing and seal and does the bushing slide right over the shaft without taking the cover off or do I need the collar as well ??This  is driving me insane and of course the great post office lost my package with the seal in it The picture is of the seal that was leaking when I got the quad a few weeks ago and one of the first seal I got from ebay that still leaks  Thanks in advance
