Early 80's movie name. Need help. Skinemax

[jojo2013]

I saw a movie back in the 80’s one late night on one of the movie channels and will never forget it.  I was a teenage boy and loved the soft-core/nudity that the late night movies had to offer.  I think this movie made me the boob man I am today.  Anyway the movie was about a female cop/detective and she drove a Trans am or something.  She was a brunette, very slim and had very, very, very large breasts for a woman her size.  There was a shower scene that I vividly remember where she and another woman (black) where showering and each had amazing breasts.  It was a poorly shot movie and the script was just as bad.  I think the point of the movie was to showcase the woman’s breasts.

Sounds like STACEY.
