My 65 Skylark convertible has a rust perforation on the left 1/4 panel in the corner where the driver door lower corner closes and fits into the 1/4 panel. I located a donor car that the owner is willing cut the piece out but it's a two door Skylark. Is a convertible and a two door Skylark interchangeable in this regard??? Thanks for any help.... I also have a post in another forum regarding same...... Len
