Product review (4 stars): these knobs worked on my old GE range.. ...
these knobs worked on my old GE range..although on the oven control knob I had to modify it to fit..you get two types of inserts to work with..grey and black..the gray ones are about an inch long..the black are 1/2" long..i used the gray on all knobs except the oven knob..the shaft sticking out was too short there so I inserted  the black into the oven knob an glued a gray on top of the black so to make it longer so that it would fit properly
