Yellowbird came after the Redbird in mid-1980. Code W73. The body color code used is 56 and 37 for the rocker. The stripping is gold. Contrary to what one might expect, the interior is not yellow, but camel. The finish of the dashboard recall the T/A Gold Edition. Unfortunately, there is no production figures of these special Firebird. These are more than collectors!
