hubs for mazda B2600 4x4

NO

Not even close.

Hi, I've got a '93 4x4 B2600i pickup and trying to remove the outer hub body to gain access to the inner and outer wheel bearings. There are 6x 10mm tapered bolts holding on each hub body, several came easily, however several have been rounded by the previous owner. They simply wont come out! 1) any ideas oh how to remove? 2) where can I purchase replacements?

Buy a cheap six point Socket that will have to be driven on with a hammer, in an attempt to gain any purchase left. If not, a good welding shop can tack a steel rod to the exposed portion for the same purpose. Good luck!
