kent alloys 2 different types

[keri]

hi again another query on the kent alloys it appears that there are 2 types of wheels with slight differences on the center outer edges just above the fan sections where the finish seems to smoothly curve over and into the outer rim square holed section the other wheel has a machined flat section then another flat machined section that goes into the square holed section my question is which is the one for a 1975 xjs there are different numbers on the wheels does anyone know
thanks
