Are the universals on the double cardan side the same ones as for the yoke side?
I see Rockford has different numbers but Rockauto does not differentiate.
I guess if my reading comp was better I would have seen this part.Precision to Rockford
important cross reference page....
the 407-10 u-joint in the CV portion of the driveshaft is 'unlisted'....according to this page, it's a Precision 513
Precision 387 is what's used in the 'other' areas of the driveshaft (non-double-cardan portions)
