You'd have to desribe it better than "A 280" Cuae there was 3 or more styles of switches for the 280Z's between late 74 and late 78'. The early models had small 9-pin connectors, similar to the late 240z and all 260Z's. Then they changed to a 10-pin 9-wire connector around 76?ish. The Turn signal went from the 240Z/260Z style to a solid metal chassis. Value depends on the market. There are plenty of them out there and not a big demand for them (I know, I have tons and no interested parties as of yet) Price them according to what people offer and their shape (good/bad, dirty/clean etc/etc.... I sell my completely rebuilt ones for about $75, where as the 240Z switches start at about $100 and go up from there. Dave.
