U-Joint Size?
1981 Half Shaft U-Joints. My stock U-Joints are Spicer P-621 (apparently discontinued)
Should I get the Spicer 5-1330X (Non-Greaseable) or 5-1310X?
How about the driveshaft?
I found this list on another post. Others can corroborate but I believe it to be correct:
Halfshaft 1980-1981 automatic 1330
Halfshaft 1980-1981 4 speed 1350
Halfshaft 1982 1350
Driveshaft 1963-1967 all 1310
Driveshaft 1968-1970 4 speed 1310
Driveshaft 1968-1970 auto 1330
Driveshaft 1971-1979 all 1330
Driveshaft 1980-1982 rear u-joint 1310
Driveshaft 1980-1981 4 speed front 1330
Driveshaft 1980-1981 auto front 1310
Driveshaft 1982 front 1310
