Factory e-brake connectors for late 69 Camaro

[NorCam]

Going through the Z/28 I recently picked up and looking for anything irregular in terms of hardware under the car. One thing that caught my eye is the rear e-brake cable connectors. My understanding was that 69's received the DD marked connectors but I'm not sure if that applies to a late car such as this?

It currently has a matching pair of rear cable connectors that appear to be original to the car. They are a bit crusty and I want to leave them that way but don't see any markings such as double D's. In looking at them further they both appear to have wings at the center of the connectors that stick out about 3/16" or so. Were these correct parts issued on a late car or should they have the double D marked connectors? I have a spare set of the D marked parts here but don't want to change them if these are the right ones used on a Nov 69 built car? Anyone know for sure?



Here's what is on the car and appear to be original. Note the side wings?


Here's the spare double D marked ones I have. No side wings on these. Swap them out or leave alone?
