Are dart sports mostly gone

Is it my imagination or have dart sports mostly disappeared.

I don't know why 2010 stands out to me as one of my best car years in my life. I was looking at a 75 dart sport in perfect original condition for a thousand bucks. My dad said, I should look for something older, so I did.

Seemed like original dart sports were around and they were no big deal.

Now I'm trying to put together a 74 L code 360 dart sport and seems like dart sport specific parts are gone and without a trace. Taillights are nearly impossible to find and the breed of car just seems very seldom seen. I really don't think I have ever seen one at a car show. Maybe a scarce few sightings over the last 15 years.

I am wondering if they were low production or what happened to most of them?
