904 pan is almost square and the 727 has a kick out on the side.
You probably have a 904 in that car.
In any case, do yourself a favor and get the gasket for the 42RH.
It is rubber over metal and is reusable.
If for some reason you have a 727, the 46RH gasket is the one you want.
Sealing a pan gasket can be a bit tricky if you are not familiar with doing it, and the reusable gaskets work really well.
