I figured out what is wrong.  Called jennair they gave me a part number.  I matched it to the identical partnumber if this bulb which Ive ordered previously.  They do not sell the older styles anymore.  I'm guessing now they want you to purchase the entire unit with housing so it takes the smaller bulbs.  I agree this is obsurd and to me they should have created a whole new part number for that.  But instead,  it is incorrect.
