GE ice maker. I have a GE Model TPX24BRBB WW refrigerator. The ice maker would notstop making ice

Question

I have a GE Model TPX24BRBB WW refrigerator. The ice maker would notstop making ice unless the bale arm was lifted clear up to the offposition. I was advised that it could not be fixed and to replace it.The original IM had a GE part #WR30X328 I was sent the new one (part#WR30X10061). Everything seems to fit except the the fill cup that camewith the IM is for a side fill or can be moved for rear fill. Whenpositioned for rear fill, the fill tube would have to come out of theback wall between the mounting screws. My fill tube comes out to theright of the RH mounting s***w. What am I missing?
