1965 Dodge Dart Charger

DS, I think I'm voting with Ulf on this one. In the FPC excerpt you included it shows black knobs for P,D,C-L (low line) cars. The listing also doesn't show much in the way of other specific car lines (V, L, Y), so I'm likely to go with "chrome" when there isn't a specific interior colour to co-ordinate with. Given that V/L models all had painted upper door shells, and there's no yellow knob listed, I think the chrome knob would be the part of choice. Gold knobs would look dark & discoloured against the yellow paint. Also, what colour do you think 2486 660 would be?

The way I read that chart, all A & B body cars used either Red, Gold, Black or Chrome lock buttons. There may have been a callout in the Trim Graphics book for 1965, but I don't have one to check against. I suspect it came down to personal choice by the operator who installed the knobs on the threaded shafts.

All of the colours of lock knobs shown under the "C" body cars used the colours where part numbers are listed. And Imperials all used one knob regardless of interior trim colour. I suspect they were chrome but the chart isn't exactly clear about that.

The "star" symbol in the "Per Car" column indicates "Use as Required". I'm also thinking that Yellow non-GTs may have gotten gold knobs, but that GTs were called out for chrome knobs.

Until someone finds unmolested GT cars with Gold knobs, I'm going to stick with voting for chrome.
