Just thought you guys could use the info. I installed a AWD 1993 aerostar aluminum driveshaft in my mustang. I didn't need the #353 napa u joint to adapt my mustangs slip yoke to the shaft. I bought a stock u joint for the 93 AWD aerostar and it fits. My mustang is a 1982 I do believe the older four eye mustangs use the same U joints as the aerostars.
