I know. Thats why i said carrier also. Unbolt the whole electric sending unit. Take it out and throw it away or what ever you want to do with it. Take your Z's speedo carrier and cog with the appropriate cog in it and stick it in the hole! you might have to cut a new retaining slot in the carrier that is 180deg. from the original slot. This is because the sx tranny has the retaining bolt 180deg. from where it is on the z tranny.
