The spider gears are stripped out in my diff and i was wondering if anyone knew if you could just get those gears or if you had to get a whole diff? Any info or part numbers would be very helpful, thanks in advance.

 

What year of car? You'll need to specify.

You can get part numbers out of the parts fiche. Go to a Mazda parts dept. to see if they're still available.

 

93 twin turbo, sorry for the lack of info.
