Frozen Manifold Heat Control Valve

I'll look for the grooves. Layson's is local to me, I'll see if they have the clips too.

Dude. No. Not unless you want to massively overpay. We're talking about ordinary, standard hairpin clips. Hardware store, outta the Hillman, Jandorf, or Dorman drawers. Like this or this.

Don't go running to throw money at specialty boutique suppliers for standard hardware items. And think very carefully and do a good bit of research before you decide to spend money at Layson's for clips or anything else. See, for just a few examples, here, here, here, here, here, here, here, here, here, here, here, here, and here. Much of what they sell is not of their own manufacture; a large proportion of their product line is bought elsewhere and marked up. They're almost never the only source for a part; see here for a listing of some more reliable vendors.
