The right side CVs connect to the intermediate shaft. More than likely it will need to be replaced as well since they rust together and the splines are either worn badly or rusted up.
Cheapest place for OEM intermediate is firstname.lastname@example.org
, 70 bucks plus shipping or call 800-270-5224.
Also NAPA has the best remaned CVs 60-65 for them with trade in of old one.
Forget Autozone and those other places, not good, some are made too short etc.
But anyways if you are doing one do both pieces, CV and intermediate. I've done several so far and no problems later
If you need any help let me know, I'm only 30-45 minutes away from you and like I said have done quite a few of them
