distributor and rotor wrong size

Hi guys I was wondering if you could please lend some advice. I have a 1991 JDM Toyota Soarer uzz31 V8 that just had major service done. Same 1uzfe engine as LS400, SC400 in USA as you likely know. 1910250020 is part number for JDM rotors. 1910150020 is part number for JDM distributor caps...
