55 chevy truck trim codes

Hey guys, are the trim codes for a '55 Chevy truck the same for a '55 Chevy car, or is it a whole different ballgame? If so, where can I find information on available trim options for a '55 Truck? My searches keep coming to dead ends . . .

 

Probably a better question to ask over on http://67-72chevytrucks.com/vboard/forumdisplay.php?f=13 There are a bunch of Taskforce guys there who know every trim code and option on those trucks. And several of us are on both boards.
