It just looked that way to me when I first seen the pics, but like 80LT1 said, can it even be put together facing the wrong way??
I know I've ran that across my mind before as I was putting my clutch together, and if I remember right, it won't even allow you to goof it up... so, I really think it was something else.
I had a brand new Clutch Masters stage 3 or 4 (can't recall) blow up on the dyno while James Thagard and myself were tunning my Z, and it blew a hole in my bellhousing.
One of the little rivited straps that hold the preasure plates friction surface let go and it just blew itself all apart. It had maybe 3,000 mi on it.
Anyways... I feel for you, and hope you get it back going with out to much down time.
