Product review (5 stars): Inexpendsive replacment glass for jenn-air
Perfect!  This Whirlpool part number 7920p201-60 was an exact match to the glass on our Jenn-air range.  All you need is 1/4" nut driver to install this glass onto your 2-burner heating module.  As others have suggested, remove the screws and lift the glass off from the top.  That way, all of the other components stay in place in the lower metal pan.
