GE Filler Kit Cooking Accessories JXFILLR1DD

I have a JGSS86SPSS with a 1.5 inch gap between my stove and my wall - how is this 5/8" going to fill that gap? Just hang in the air? maybe get 2 and they can hang side by side. Sorry this product is simply no good for a filler - at least for me.

We have the JGSS66SELSS stove and ordered this trim kit because it shows it as an accessory for this stove. We need the longer rails for the sides but (1) is notched out. Is there a way of getting just (1) long piece that is not notched out?

I have the 30" Profile gas range in black stainless (PGS960BEL1TS) and ordered this as it's listed as an accessory. It is not compatible. The color is an exact match, but 3 of the strips have a notch cut out on the side against the oven which makes it pointless. If you zoom in to the pic you can just barely make it out. Interestingly if you go to the plain stainless steel version of this filler those notches are not present. No idea what range those notches are meant to accommodate but they won't work for the PGS960BEL1TS. Also, in general.. two of the strips are about 21" long. Can't figure out what one would use those for.
