I need to know what front rotor I can use that will give a 5 on 5 bolt pattern and use on a 75 to 79 Nova front spindle. Rotors must be 11 inches in diameter to use stock calipers and pads. Early 70's pickup rotors are too big in diameter (11.88 inches). Any help will be appreciated.

Why can't you use 11.88 rotors? What exactly are you trying to achieve?

I would think the later GM tall-spindle applications with the 11.88" [12" nominal] rotors would be a great option for you, spindles and all since these applications came with 15" wheels. You can use the rotors from the 91-96 B-body application with are 5x5 and have the larger outer wheel bearing. Not only that, you shouldn't rule out the D614 pad since it's a direct swap for the D52's and has more pad volume. Spindles should be a direct swap basically.

None of the early-70's B-body stuff is going to work as that is all basically the same as the 1/2-ton PU stuff.
