I saw one called Buy Auto Parts which looked interesting. Too bad it didn't turn up for you. You'll be able to get the numbers off that bearing, then, if the bearing swap doesn't work out.I couldn't come up with anything using that search criteria.
Today I took the torque tube out of a Chevy Equinox. The tube is much shorter, but for the $30 I paid for it, it's worth a gamble the bearings are the same. I'll be sure and post the results with pictures.
