Had to drill out the little dimples for the bolts and the fan guard that goes on top to stop debris didn’t screw directly into the fan like the old one. B ... Read more ut I was able to attach the guard to the engine cover/piece that houses the air filter with a plastic bracket/retainer that was already on the engine. Overall, easy install and fit just fine once I determined how I wanted to attach the fan guard
