I feel like a fool. You all are right. The bell housing is indeed separate. The tranny is so dirty that the seam between the tranny and the bell housing is invisible. However, the bolts inside the bell housing tell the truth just like you described.
I just got home from work and went immediately to the garage to check it out. I don't know about converting to an external slave. It looks like the bell housing would have to be replaced with one that could handle the additional clutch linkage, the external slave and a normal throwout bearing. Even so, it would be worthwhile.
So let me aplogize a thousand times. You guy's know what you are talking about and I'm still learning. I like to learn. Thanks for putting up with me.
