So, where did you end up finding the centering ball, could advanceauto order it for you? I can't seem to find them anywhere.

 

The neapco part # from advance says it will not fit the 2004. But it also has the ng at the end. Do you have the actual part # on the one you ordered by chance?

 

Okay, I ended up finding the sticky that says ignore there part#, so it should work.

 

I haven't gotten the part, but mine is probly different from yours because I'm rebuilding an aftermarket shaft that has larger/different components.

Is yours a stock driveshaft? Does it have grease fittings on the u-joints? If so, you'll probly want to measure the u-joints to be sure you're getting the right parts.

I ended up ordering my centering ball off ebay. $35 shipped. I just searched for 'neapco 7-0081'.
