No one can answer this question.
If it's stock 68 brakes or later disc brake swap will matter.
Until you have the car and can verify wheel stud bolt circle and diameter you will be guessing. Remember, stock is has 10 left hand thread studs and 10 right hand thread studs and finding proper LHT nuts can be tough.
IIRC, stock is has 7/16 studs.
He clearly mentioned 5x4 pattern. So later brakes are not in the equation.
Just a guess, the wheels won't likely require that uni-lug nonsense other wheels have as they are drilled single pattern.
Someone on another site just had issues with the suggested lug and what was actually needed on a cragar wheel purchase. There are a couple different series of these S/S wheels in production.
