Sorry another wheel question!!!

[ukregal]

I want to order some 15 x 8 (rears with 4.5 rear backspacing ) and 15 x 7 (fronts with 4" backspacing) for my 78 Regal. I have searched on this site and some people say they will fit but some say they will rub. Can anyone tell me one way or another if these will fit ok?

Thanks
Mark

I have 15x8 in back but IDK the backspacing. I will measure it this weekend. I've got GM 14x7s in front. They'll knoch the weights off on the control arm so I have a lil 1/4" spacer. 15s shouldn't have that problem cause the rim is 1/2" farther from the control arm.
