68 dodge dart gts

Hey Guys I've got a 68 GTS that needs Major body metal replacement ie, quarters, tubs, floor, and trunk parts replaced. I just wanted to know if a 68 has any other body#s stamped on it besides the core support? I don't want to cut out all this metal and start putting in new AMD metal until I'm sure about the stamps.I know 69's had trunk vin#'s and 67 did not but so far I haven't seen any #'s on my 68. Any help here would be Great :)
