i have a 78 280, and am interested in installing one of the diamond pattern vinyl interiors from the old 240s. i've always liked this pattern, not to mention that the guy who owned my Z before me did a shitty job of attempting to recarpet the interior. should these vinyl patterns fit in my car ? i know that alot of the old 240/260/280 parts are pretty much interchangable. just want to make sure that the vinyl will work before i remove a set from a 240, tear my car apart, and try to install in mine. thanx for the advice.
