Here's the bellhousing installed with the clutch fork and the throw-out bearing visible.
STOP!
What I didn't know here, but found out later was that the clutch fork needs to be cut off! It's too long and will not fit into the tranny tunnel (Here is a picture of the "bind"). Click on the image to see about where the cut needed to be made. Also compare this with the same view after the clutch fork was cut off.
