Product review (3 stars): Watch the sizing of the D-shaped mounting pins
Granted, our stove is from the 1970's. But these knobs are a REALLY tight fit. Even after scrubbing the mounting pins on the stove, they were a bit tricky to mount. But ultimately it worked. You do probably get "extras" if you don't mind a possible mismatch between markings & function. But for the price...not bad!
