Tire size on front with factory swaybar setup

[slantysix]

Anyone know the size of tire that would fit on a 72 Scamp with 15" police wheels and a factory swaybar setup on the front? The calipers are mounted on the rear and swaybar on the front from 69 dart with factory lower arms with factory swaybar tabs. What is the widest that will fit without hitting the swaybar with no rubbing??? What are some sizes of tires front and rear without rubbing with police wheels?? 73 and up front disc and 8 1/4 rear. Any pictures??
