Yes, maybe a Unicorn !!! But I'd like to have one. I was told they do exist and they are very rare. It's almost as if they may have only been made for 3 weeks or a month. It seems I read it in a book and why I believed it. Now you know if I had read it on the internet, I'd know for 110% positive it was true. But here's what gets me and makes me think that book is wrong or it's a unicorn, or maybe it was just a GM Prototype even as they made changes at the trans R&D factory, Pressure taps ended in 86 right? In 87 the case it different and they ARE NOT backwards compatible without heavy mods. So, it's not like in 87 they used the left over 86 cases. That's what makes me think they REALLY do not exist. But if they do, I want one. You smell what I'm steppin' in there?
