The alignment dowels for the crank seal housing are listed as "not serviced" (therefore no part number) for most years of the 2.2/2.5.
In the 1981-83 catalogs for 2.2 and re-starting in the 1992-95 catalogs for 2.2 and 2.5, they come up as 5203466: DOWEL, Cylinder Block to Crankshaft Seal Retainer.
Widely used to this day on many engines.
