When fitting the T3-2-949AU, confirm the Ford Mustang 7.5-inch or 8.8-inch differential companion flange uses a 2.000-inch pilot and a 3.500-inch bolt circle with 4 x 0.516-inch holes. The 1.550-inch CJ-to-flat dimension affects driveshaft working angle calculations — account for this when measuring driveshaft installed length.
The T3-2-949AU is machined from 6061-T6 aluminum, reducing unsprung and rotating mass compared to a steel flange yoke. The 1350 series U-joint interface is appropriate for Mustang driveline torque levels. Match bolt circle diameter and pilot diameter against your specific differential before ordering — 7.5-inch and 8.8-inch Mustang axles use the same bolt pattern but confirm pilot diameter on your specific application.
