Keenan- the '75 Nova is 2" wider than the '68-'74 Nova. It will work but it'll be tight with the wheels/tires in the front fender openings. I used a '79 Camaro clip (same as '75 Nova) and used 15x6 wheels with 4" backset. 205/75/15 tires. I also tweeked the fender openings a bit and have adequate tire clearance. I don't like the idea of using 1/2" spacers for the rear wheel clearance because of safety issues. (Some guys will argue that it is safe , but I don't agree.) I added mini wheel tubes in the bed so that the tires don't rub on the bed sides. (Camaro 10 bolt axle.) Basically you need 1.5"-2" of clearance and they'll never rub.
