Product review (4 stars): patience is a virtue
Even if the knob fits your stove the temperature numbers might not match the original.  Lux Products encloses a catalog in the package with 36 overlays.  Find the one that works for you and snail mail a check for $2.00 to New Jersey. (No way to order online!)  A month later a slightly bent overlay arrives from Texas. The knob looks and works like new.  From the original Amazon order date until the overlay arrived was 47 days and was well worth the wait!
