Tupac Actor -- That's NOT Real Tupac Autopsy Pic in Banned Music Vide -

The ghost of Tupac Shakur is haunting Wyclef Jean ... whose music video just got yanked from YouTube because someone thinks it features a grisly pic of 'Pac's autopsy -- but TMZ has learned it's just an impersonator with great makeup.

The scene in Wyclef's "April Showers" video looks eerily similar to an infamous photo of Tupac's corpse -- partially cut open during his autopsy -- and published in Cathy Scott's book, "The Killing of Tupac Shakur."

Scott tells us she's convinced the image in the video is the real deal -- she's the one who complained to YouTube -- but Tupac impersonator Richard Garcia tells TMZ he's actually the stiff.

Garcia says he was hired to re-create the autopsy for the video's anti-gun violence theme ... and it required 8 hours with makeup artist Autumn McHugh -- even though he only appears for a split second.

We told Scott about Garcia's role -- but she insists the image is TOO perfect, and must be the photo.

Our guess ... the video will be back on YouTube soon.
