Re: ADP4501
on disc/diagram its confusing
diplomat/stoves
its show 733 for upper seal but there is no part number for 733 in list.
734 shows as bottom seal 031797200 before oct 2000
and 032147301 after oct 2000 .
normally u have to cut these down to fit as they are to long.
i would guess reason there no number is that they are both interchange able from top and bottom other than the lengh that has to be cut tho this is a (guess ) hope this helps
