Im having a driveshaft built and need to know stock joint size. The guy sia dhe thinks it is a 1310, he said find out for sure. he is building it with 1330 on the shaft side and 1310's on the trans and rearend side
Stock should be 1310 front and rear. If you have 1330s put on the shaft, but keep the 1310 on the trans and diff yokes, then you'll need the Ford Racing 1310/1330 hybrid joints. Those are about twice the cost of straight sized joints.
