Thanks Tim. I had done my research as far as that goes (well, just one of those useless things I remembered from working for Kevin Enders as a kid). I am all set up with a flywheel and balancer, I just needed to make sure I had the correct bellhousing. For an update, I took my car to get it inspected last Saturday, and the guy that owns the garage is quite the collector (looks like Sanford and Son's place), so I just happened to mention I was looking for a bellhousing for a 168 tooth flywheel. He took me over to the back of an old Dodge van and pulled one out. Said he'd never use it, and sent me on my way.

Thanks to the site from the link Rich found for me, I discovered that the piece I got was a very good score.
