Door caps?

I have replaced the original contact door switches for the interior lights and seat belt light with an Alfa switch replacement I found recommended on this site (note switch in the photo). The switches however will not depress when the doors are closed because they fit neatly into holes in the door panel (see photo). I had my 1978 308 painted. I assuming that the holes are supposed to be filled by rubber or plastic caps that fit into the holes and the painter removed and never replaced them. Is this correct? If so, Does anyone know the part number I need to look for to purchase replacement caps and/or anyone know a source for them?

These might work. They are plastic but they are also available in metal:

Thanks very much!

 

I think they are on Tav 107 for the QV, part 40127409. Ricambi seems to have them for about $9 a pop. I need a couple also.

 

Thanks very much Brian!
