Product review (5 stars): If you're having trouble finding a good "universal" fit set, just buy the right ones the first time.
You'd be surprised how difficult it is to come across these guys...THE RIGHT ONES!  I bought a cheapie "universal" mount set from the hardware store down the block...too small of diameter.  I looked up another model at Home Depot...drove down and it was the correct diameter.  This second set had notches cut out of the bowl which didn't match up with my coils (though it said "Universal" for everything except GE stove tops.

Finally just told myself to just type in the model number online and order them here.  PERFECT FIT for my model stove top!
