On the driveshaft, the stock driveshaft will need to be cut 3/4" when the stock 71-72 8.5 rear uses its 3R ujoint yoke. There is a very tough to find 12 bolt 3R yoke that wiil shorten that distance up some, not avail from the aftermarket, though.
On sourcing a suitable core, stay in touch with locals/regionals who buy & part '71 & 72 Cutlasses & Skylarks. The core rears are out there, am still finding them.
