Rattletrap, Check out www.oldgmctrucks.com, click on to Tech. stuff, then click on to Factory accessories 1954, and you will see a picture of both factory heaters for 47-54 Chevy & GMC trucks. Yours should look like one of these ,unless you have one of the after market brands that was available back then.
