This is what it looks like on my '79 P200. No retaining ring when I took it apart. The tabs have thin locking tabs over them.
Great, that's what I needed!

I really hope this solves your problem. I found that the tabs on the early P cases were not as accurate for getting the bearing to align compared to the PX and LML cases. I had to tap the bearing a little here and there to align it and get the crank turning smoothly. You're doing it right though…making sure everything turns smoothly instead of slapping it together and hoping for the best. Consider all the case splitting an investment in the skill set. The practice will serve you well for future engine building.

It spins freely now after using the clips instead of the circlip that I mistakenly installed.

That circlip goes on the other side securing the bearing. And the seal goes next…

Yes, there always was a circlip and seal on the flywheel side.
