I have a 67 dart and had the same problem. I ended up changing mine to a 69 truck( less trim) but then found a place called Obsolete Parts out of Fairmont Ga. they have a few 67 tail panel trims for a 67. It should be a panel with the gt logo on the right, like you said and then a four piece upper and lower trim. I found out that the four pieces could be used on any corner because they are all the same. The parts place has a website and they are good people, all they deal with is Mopar.
