The failure of the diferential mount you describe is not uncommon on early SPF's, particularly cars with big torque, big blocks. This failure is also likely the cause of your CV failure. That mount was redesigned for later cars and is now much stronger.
I don't have pictures, but if you could get your car to Michigan,
http://buckshotracefab.com/ has experience in repairing this mount in a manner that will not fail again. Their phone number is 734-654-1194
