The spoiler that's on my car, some referred to as whale tail, but really was only available as an add-on with SLP package. It was never a true GM oem part but at that time SLP was trying to offer "tuner" packages thru dealerships for the Monte but it was short lived and never really took. I have dealer brochures I believe I've posted here but can post again for historical purposes. Haha
Some have also referred to this spoiler as an Intimidator III spoiler but I only know it as a whale tail or SLP variant spoiler.

BTW, to o.p. nice ride!!!! Keep up the good work!

Nice. Like the factory aero package. One option wished I had.

 

Thanks! You can swap everything out if I'm not mistaken, however, those parts are becoming harder and harder to come by.

 

I'll let the next owner do it.😊

 

blasphemy!!!!!
