Thank you so much for posting this.
My VNT-15 Rabbit project was put on hold because when I got it running the turbo was screetching.
I thought I had a second center section to put on it but it was different:

Basically buying an exhaust manifold for it, great timing, I just found out the other center section won't work last night.
Thanks again, looks like it's mine.
