After a year of searching for parts, I have my 1987 Dodge Ram 50 2.0 engine out and torn down to the block. Looking over timing components, the OIL PUMP SPROCKET has been rounded out and there is no longer a flat to engage the oil pump drive gear. Looking over at Dodge diagrams this part does not have a part number. It is clearly shown in the shop manual, without number. This the same part in a Galant?

1) Any ideas on a part number?

2) Anyone have one?
