Brian Blankenship Posted December 4, 2023 Share Posted December 4, 2023 Looking for exhaust manifold gaskets for '57 b61. Pretty sure it's a 673 with no turbo. Quote Link to comment Share on other sites More sharing options...
Solution mattb73lt Posted December 7, 2023 Solution Share Posted December 7, 2023 You should be able to get those pretty easily. Mack, NAPA, Fleetpride. Several Mack engines use those, END-673, ENDT-673, ENDT-675. I don't have a part number for you, but they shouldn't be to hard to track down. Mack 573GB257A, 573GB260 maybe? 2 Quote Link to comment Share on other sites More sharing options...
