What is needed for connecting the exhaust pipe to the exhaust manifold on a 59 235? Pipe was loose on the two mounting bolts and when I removed it there was the remains of a metallic donut. I'm assuming I'll need that, but do I also use a two hole gasket for the flange as well? Napa site shows both the donut and a gasket, and I think my 1963 Master Parts books does as well if I'm reading it correctly. Thanks.
