On my all-Wilwood braking system (front and back), I used Porsche 911 (early version with 15" wheels). They fit stock AND Wilwood calipers, but need a thick aluminum spacer/adapter to bolt on. The rear discs also need lathe machining to fit the Pantera uprights and axle flanges. The ODs match the Pantera discs, too. Larry Stock at PanteraParts.com sells these.
