'77 or '78 Riviera WITH AstroRoof

I know they're rare, but that's what I am on the hunt for.
Any leads, or if anybody here has one they'd like to part with, post or PM.
Looking for one in any condition. Drivable is preferred, but I like projects, too.

Thanks guys!

 

You should check(If you havent already)if this one is still around.

I'm almost positive that is has been sold.
BUT, almost isn't enough for me.
I'll have to PM him.
Thank you!
