LO23 and BO29 hood scoop question

Did they come with 2, 3, or 4 hood scoop supports from the factory? I have seen several variations. I am guessing 2 and after issues, more were added by the racing teams.

They came with two supports from the factory. Owners added more because of flexing at high speeds. Owners also added more hood pins because of hood lifting at high speed also.

Want to pick up a new one?

I had one on a Dart I had years ago. The previous owner used 3 supports, I had to add hood pins in the middle (6 total) because it was a gutted hood and it wanted to lift off the car at speed.
