It was the perfect replacement part and was delivered promptly.
This was a gasket for a machine that is almost 40 years old. So happy to find it and get my old Troy-Bilt tiller repaired and ready for spring.

Remove the tiller housing cover. Then the old gasket. Clean the area where the gasket is located. Place two screws opposite from each other in the cover then place the gasket on the screws. Then attach the cover with the gasket to the tiller.
