Product review (4 stars): Great company to order from
Great item, exactly like the ones I wish to replace.  I have a C202 Jenn-Air, about 20 years old.  These knobs fit a "D" shaft...I have something other than that. Who knew? Company refunded my money promptly upon return. Just a head's up about the on-off shaft on those older Jenn-Air cooktops.
