Hi Char -
I know this off the top of my head. He is buried in Westwood Memorial Park, just off of Wilshire. His flat headstone has a pyramid with an eye in the middle (I think) and the dates of his birth and death (not sure right now), but the death date was followed with a question mark, which I believe is a hint as to his belief in re-incarnation. I took a picture of this, along with many others in this fascinating cemetery. I believe my first 'visit' there was around 1989, so he's been gone at least since then.
Mr. Conte was an exceptional actor.
