I measured the drive shaft for my 66 Dart 6 cyl. 904 tranny. which I just put a 8 3/4 .489 big yoke.(6 cyl. 904 shaft to long)So I tried the 73 swinger 318,904 with 7 1/4 rear(driveshaft),and it,s the perfect length.Now what I need is the part # for a crossover u-joint so I can change from the little u-joint from 7 1/4 to the .489 (big) yoke on the 8 3/4 rear.Does anybody understand what I,m doing here?Any help would be appreaciated.Thanks
