If we are still talking about the small block bellhousing it only has a stater mount for a 130 tooth wheel so you don't need any of the starter mount kits that big block bells use.What crank flange do you have? A few of us Moparts guys designed and built a rock solid tool for checking bellhousing alignment.It's for a six bolt crank and could send it to you for some short term use.My block will be back soon so I will need it too.Once you determine what dowel you need order them from RobbMc he belongs to this web board and his dowels are actually made for a Mopar not a Ford the the ones Lakewood sells.
Let me know
