I'm hoping someone here can help me out with this.

I could have sworn that somebody (I think Clarion) made a 36" sub a
few years back, but I haven't found any reference to it searching
newsgroups or webpages.

If they did make one, I would really appreciate any information that
can be provided whether it be reviews, T/S parameters, or hopefully a
link to where I can find pictures of it.

A coworker of mine thinks I'm completely out of my mind after I
mentioned it to him. I don't dispute that I'm crazy, but I'd like to
show him that there really was one.

PA subs are that big. See if they have a professional or PA catalog.

I'm not sure why you'd want such a large diameter sub for a car. If
you've got lots of room, get a sub that's more efficient in larger
enclosures. Adire Audio has some good ones - Shiva, Tempest, and
Brahma. If you're insane and have $5000 to burn, they'll build you a
custom Parthenon with up to 16 cubic feet of displacement.
