I think that 31150 would work. Just screw in your own inlet and outlet parts to the "back" and "front" holes (where those red things are?)
The burners are on Amazon. They now have a metal cover over the orifice then the screen starts. Works the same.
The sparker set they sell now has bent probes instead of straight like OEM. I was able to get separation above the screen by using washers as shims to tilt it up a bit. Hard to explain. I have a photo of that somewhere: OEM straight set seen there too. The straight ones were too far above the new burner screen and the new bent set was touching the screen, but is ok shimmed up as seen there.
