Windshield Wiper Trouble - 00' Rodeo

Hi, I was wondering if anyone could assist with this:

The windshield wipers won't work at all, regardless of stalk position. The motor still makes noise but no movement. I did searches and apparently I can't simply replace the bushing that is probably worn, instead I'd need to replace an assembly of sorts: http://www.automotiveforums.com/vbulletin/showthread.php?t=535524

Anyone know if I could find this assembly in say...autozone, pep boys, etc?

Is that even correct, or can I get by with just a bushing/linkage w/e?

Thanks in advance,

Ricky
