Does anyone know if the Fenton's Patrick's used to sell were intended for trucks or cars?

Are they different?

NAPA lists flange gaskets for the cars as graphite-looking rings and the trucks as being flat with two bolt holes. I have been using truck pipes and the flat gaskets but they have burned out several times -- yes, yes it's been 20 years but it's still an annoyance and NAPA shows the nearest stock of them in Illinois. I'm in Washington State. They have a dozen donuts in stock locally. I have only one left in my own stock.Maybe it's time to change pipes if that works. That's no small things as they have to be custom bent and all.
