Look for GT only options and look for a build tag and broadcast sheet . What does the interior look like ? Does it have halo bucket seats ? If it is a late 84 does it have fog lamps in bumper cover . Does it have a locking rear-end ? Does it have them stupid little traction bars on the trailing arms or quadra-shock for a late 84 . Is the GT badges where they need to be ? If all else fails you could contact Kevin Marti for your own report .
