Review on Hedman 21110 Outlet 3 Bolt Reducers by Eddie Gordon

Just bought this for my 1986 El Camino with a 2001 GMC Savana Vortec 350. They looked and felt great quality, the gasket felt and looked like it would do a lot but the screws looked and felt questionable. I know you don't need screws to be the best because every hardware store has nuts and bolts to replace them, but it would be great to save yourself a trip to the store.
