1966 toronado lower ball joints?

HEY, JIMMY HERE FROM LONG ISLAND. Just saying hello and was wondering if anyone would know if the lower ball joints on a 66 toronado are the same as 72-78 toronados? Also would anyone know what the trw part number is for them? i have been looking on the internet to see if i can find a part number etc and cant seem to find it. i also was swearching sites and some of them mentioned a possible taper diameter difference? Any help would be really appreciated . Thanks... Jimmy
