OK, so I did a bunch of research and made several phone calls. All of the research pointed to the PART NUMBER: W10396546
. Now this is the BLACK glass top not the Stainless Steel one. So this is for the JIC4430XB (B-black). Jumping ahead a little I also check with a local parts place and confirmed the part number!
Now for the install. I found the repair manual which only talked about 6 torx screws holding the glass on and that's it. What it wasn't clear about is if there were any sensors, etc. attached to the bottom of the glass or stuff like that. So I managed to get access to a repair shop and one of their service folks. He confirmed that there are NO HIDDEN issues (sensors, etc). That it is really just the 6 screws (2 on each side and 2 in the front) and then the back lifts off. He said it was/is really that easy.
Lastly, what I found is Sears has the cheapest price at $292 free shipping!!! http://www.searspartsdirect.com
