Wheel Backspacing?

[Nxcoupe]

What backspacimg on a stock 66 suspension, ie, no spring mods or wheel tub mods?
15x8 for the rear and 15x7 for the front. What backspacing worked for you?

4.25" to 4.5" 7" wheels 4.5" to 5" 8" wheels.

I don't have a 66/67, but from the discussions I have read, a 15x8 or 8.5, with a 4.5 or 4.75 bs is the sweet spot.
