On my dads D 15 Series II there is a crack in the intake manifold.  I might be able to braze it but I got to pricing a new one and I am finding alot of D14/D15 manifolds but I don't see a specific one for a Series II.  Is there a difference in them?

The series 2 manifold has a threaded in 1 1/2" pipe for the muffler to slip over. I don't think a D-14 and an old D-15 are the same as the D-15 manifold hangs out wider from the cylinder head another inch over the D-14, but I could be wrong on that. I don't know where your crack actually is in the INTAKE portion of the manifold, but if the engine runs fine and especially idles fine, the crack isn't deep enough to hurt anything just yet.

As the tractor gets worked and warms up the crack opens just enough to have to run the choke.
