I don't believe Ford made a 3.78 set for the late 32-34 rear ends. They did have a 3.54 ratio set but are quite rare. Ford later came out with a 3.78, 10 spline set for the 35-39 rear ends and you can have the pinion machined down for 32-34 bearings with the driveshaft lock pin hole relocated for installation in a 33 rear end. May require some grinding on the ring gear for clearance and installation. Look for some other discussions and methods on here and other sites.
