Summary Good fit. You will need a 3x.5 mm tap and a #40 (.098) drill to size the holes that need tapping. Be careful installing the wood screws. You may need to widen the wood screw holes slightly so they don't crack the ABS. Wood screws hold the wind barrier and the circuit board in place. Instructions Good fit.
