Oil pump gear marks?

Hey everybody
I recently bought a 904 that was rebuilt like 25 years ago.
So I'm going through it to check everything over.
I took the oil pump apart to inspect it and it appears to have been refurbished.
My question is I didn't notice the Mark's on the pump gears before I took it apart.
Is there a right way their supposed to be aligned?
I haven't been able to find any info yet.
Thank you, Mike
