Washer set for manifolds

The triangles have no spring retention property, they are there just to allow the thermal expansion of the exhaust manifold to slide on the gasket as designed, and they only work if they are installed with the proper clearance on all sides. The concave washers on the ends and in the middle are unique and should be chased down as well as the brass cinch nuts but the flat triangles should be fine. The OEM ones have a small raised center so as to help in getting the torque correct, not dragging on the flats. Could work around with a honest torque wrench and a lick of sense.
