Re: Backspacing for 15x7 15x8 wheels from 66 El Camino ok for 1st gen?
AR website lists offset of -6 for 15x7 and 0 for 15x8 for those wheels.
That would translate to a backspacing of 3.75" and 4.5", according to the chart.
I believe the ideal backspacing for 15x7 is 4.25", and for 15x8 it is 4.5".
I think you should be good.
