for the cost involved to fit commodore struts in, I think you'd be better off using the hopper stoppers kit, available in any pcd you like.
when you factor in the costs of buying commodore struts, then modifying them to suit (shortening, reconditioning, ect) it would probably be cheaper to just use hoppers kit.
I would also reccomend using the ford stud pattern, as the wheel selection is much broader.
