Lugnuts and steel rims

[BR00T]

Anyone know the standard lugnut size for 15 inch steel wheels for a vy commodore? Also anyone know where you can buy brand new steelies for cheap? Seem to be harder to find. Cant afford mags

All Commodores pre VE use a m12x1.5mm stud (except the early 4 cyl models) if Im not mistaken with a taper seat. Should be common enough and be available at any reasonable automotive outlet or wrecking yard.
