Knobs for Jenn Air Cooktop

Have an old model 2475/90ers Jenn Air Cooktop, which is so old the

Jenn Air site does not recognize. But I have seen it mentioned by

others on the net.

Years ago, a local man changed 3 of the switches, which are the

"push to turn" type with an H or flat shaft. And the "OFF" position

is at 6 o'clock. Now 2 of the knobs are broken and the other one is

in very bad shape. The fourth knob is still the original D type

shaft.

Since the knobs are not Jenn Air but probably Maytag or Whirlpool,

have found it very difficult to get new knobs. The only thing I can

find is a kit 5500-200 but it does not show that it is push to turn

or an H shaft.

Any suggestions you may provide will be really appreciated. I am

desperate.
