Nothing makes me happier than a snapped bolt in an engine block...
On the bright side I'm pretty sure my oil leak is just the pan gasket. It consisted of rock hard cork and rtv. I"m going to take a chance and leave the rear main alone.
I also nabbed a lower steering shaft from an xj in a yard today for $10. Rumor is it is a direct swap and eliminates the rag joint.
