Injector Intsall Help Please

OK got the spacers now I need help for the retaining clips. There are two ridges on the injectors that the clips can fit into. I know it is imprtant about whre the jectors line up in the manifold, but do I slide the clip on the lower(est) ridge, the one that encircles the injector or the top ridge that is only on the side where the clips hit.

It seems like it would be hard to get the injectors deep enough in the rail for the clip to hit the lower one but it is doable .

Let me know if you can please, I really want to get this thing back on the road...
