Fits 1965-73 429/460. What a cool idea, bolt on horsepower! By preventing the oil supply from splashing against the crankshaft, this neat item will give your Mustang an extra 10-15 horsepower without sacrificing gas mileage like you would with a bigger carburetor! Plus Canton's superior one-way screen design allows residual oil to flow freely back into the pan while preventing horsepower robbing buildup and backsplash! Our windage tray kits include a Canton screen style windage tray, windage tray mounting bolts, and a new oil pan gasket, all in a single, convenient, money-saving kit!
