No, I just see your posts on Tech like everyone else. I am usually only in two forums, Western section and LT1/LT4 Tech.

I have a TB, but it doesn't have the lower coolant passage portion or the top plate. So you'd be better off getting a complete throttle body.

I'll send you a pm with info for finding parts.
