Anybody running 17" Cobra Bullit rims on a Duster

We were at the track the other day (Portland International) running 150 mph with Mustang wheels hung on a 1968 Valiant. 17x9 rims with DOT race rubber. 427 inch small block pushes the car up past 150 mph on the straights. No spacers required but the car has custom hubs up front and a B body axle in the rear.
