Product review (1 stars): the product is useless to me
The captions for this product show the outside diameter of the knob. Unfortunately, it does not show the inside diameter of the portion that attaches to the gas assembly stem.  For my GE range,, the available connectors were too small.  The largest of the knob connectors was about a third in diameter to small.  So, the product is useless to me.  My stove top is a 1990 model and I have not been able to find knob replacements.
