Here are two photos of 69 Firebirds that I found that have the rear antenna (out of 100's of photos I have only 2 had the rear antenna). You can see one is fully retracted and the other is not. My 69' coupe is all original and it has the rear power antenna. I can take photos and measurements if someone wants them (it is real cold out in the garage right now though). Soon I will replace the rear quarter and so I will measure the placement off of the original quarter, and now I know how to drill the new hole. I was just wondering which retraction is factory ? My antenna is broken at the base, but from the best I can tell, it does not fully retract (looks like the photo with the partial retraction). The label on the power antenna base is not clear as it is faded and so I can't tell if it is factory or not, but it sure looks like it.. Any ideas ????
