I remember a post regarding inner wheel house interchangeability between 2D and 4D models but I could not find the post when I searched so I'm asking here. What I've got is a rusty deck lid torsion rod support on my 68 Coronet due to a leaky rear window, I have found one from a 4D car but I cannot remember if the inner houses are the same or not. Can someone advise? Thanks.
