Filed and smoothed tubocharger flange support bracket edges with Scotchbrite wheel. Turbo flange hole was undersized, opened to 3/8" with drill. Secured waste gate actuator to braket. Loosely bolted waste gate actuator mount, support bracket to exhaust flange using supplied intake gasket. Am unable to fit the lower exhaust pipe, as there is no clearance between its path and the engine mount struts.
