Product review (5 stars): Buy from Amazonand Order the Screws
Appears to work well (just installed today). I saw other reviews for this and similar parts indicating that the part received was not genuine GE. I ordered directly from Amazon and the part came in a sealed GE branded box (photo). It included wire insulation which at least one other reviewer said their part was missing.

The mounting screws are tricky - they have a split shaft and one formed a collar at the tip that made it very difficult to remove. Ended up removing the burner that the igniter is attached to in order to get a grip and to pry while unscrewing. In hindsight I would have removed that burner immediately as it made working with the old and new igniter much easier. I was able to get both old screws back on with the new igniter but would prefer to have had new screws just in case.

I wish I had extra fiber insulation to stuff behind the igniter after replacing the igniter and wires. This process seems to push the insulation back and away from the heat source.
