Y pipe flange

Hey guys,
I’ve got a 66 valiant 4 door with a 2bbl 273
I am trying to build a y pipe for it but I can’t seem to find a bell flange small enough for the exhaust manifold to connect to. Looks like about 1.5”? What have you guys used in the past? I don’t want to swap my manifold.
Yes I could buy one online. I’m in Canada and shipping is crazy right now so I’ll be doing it out of 2” stainless.
