Hah! I can't charge for this answer bec/ I don't know it
When you have a 3 on the TT, it is most likely d/rail, d/frame and body side. That is the most common combo, even for cars without a v/t - like my '69. For your car the d/rail is a given, and the body side moldings will have pegs spot welded to the body sides - making them a given. The upper row of rocker moldings are also pegged (I believe), so if you have pegs - they are a given. It's the door frame moldings that give us fits, as there is really no telltale sign that a car came with them or not. However, if you've got a 3 on the TT, and no pegs for rocker moldings - that pretty much leaves you with door frame moldings.
BTW, if someone ground off the pegs for the body side molding, and then repainted the car, you can still usually tell if the car had them. Look at the ends of the door skin, on the inside, right where the skin wraps around the door frame. There will be a hole there that was filled in, on both ends - but the door latch end is obviously much easier to see. This is because the body side molding for the doors is pegged on, except for the ends - which are screwed, thereby requiring a small hole through the frame/skin, and a unique clip inside the molding to accept a machine screw. So, look for those holes to be repaired.
