The ring sounds like a great idea, as long as it lays in the outer circumference of the recess and not the inner toward the crank surface.
Also, the spacer can go on either side of the seal, and gives the ability to shift the seal fore or aft .100" to place the lip on the best surface area of the crank. Many Packard V8 cranks have surface imperfections in the seal area. Don't forget to scuff the crank surface with 320 grit paper, as the old carbon seal makes the surface mirror like, which is not good for seating the neoprene seal.

I also used a file to "hit" the (four) ends of the new seal about half dozen strokes each, to remove the molding imperfections, as are visible on the seal posted above. Once perfectly flat, I used a very small dab of non-hardening Permatex on each end (careful not to get it on the seal lip). That may have been overkill, but seemed like a good idea. I also applied a very thin layer of that Permatex on the outer edge of the seal, where it bottoms out in the recess.

If running an Olds pump, there is another detail, but I will not bother you with that for now, unless you say you plan to run one.
