How many Swingers w/ sunroof were made in 1975?

thanks for the info. Yes it is a factory sunroof car. I checked the fender tag it's there the option code. I'm in Louisiana I've never seen another one around here. It's a 318 automatic car. I'm in the process of doing a restoration on it. I'll see if I can upload a picture for it. Should be a nice weekend cruiser when I'm finished.
