...I do have a 8.75 and I just swapped the axles so I'd have a 4.5" bolt pattern. I do have a bit more space on the driver's side. I don't remember seeing an adjuster on the axle though.
By '72 the adjustable bearings had long been eliminated. Even my '69 doesn't have them. I'm not sure why guys start adding info like that to a thread since it does not apply to your car.
