70 Formula 535

Take the springs out and cycle the suspension and see if it hits... I run less clearance than that on our shop car with a drag radial and you can see where the tire kisses the leaf spring on hard corners (this car is not really a corner carver) A floater rear and stiff sidewall tires will lessen your "un-measureable" wheel/tire movement. Id run it with the 5.75" if it meant no or lesser chance of it running into the fender lip.
Cars lookin' good!
