So I'm doing the cv shafts & the parts from O'reilly's don't match up with what I pulled out of my 99 Blazer. The cv shafts from an astrovan look similar on the Internet. So my question is this, has anyone ran into this problem? I am not the first owner, have had the thing since '03, and don't really want to spend the $$ on a carfax. Thanks for any ideas. Joe.

 

Your 1999 Blazer should have splines on both ends, not flanges.
