So i was changing my drive axle and i've managed to remove 5 of te 6 bolts that hold it to the tranny. the 6th bolt slips when i try to remove it. I was using an internal hex wrench but looking at the other bolts they seem to use a 12 sidded pattern. so i got some and tried it but they wernt the right size. i have a 6,8,10,12. well the 10 is to big and the 8 is to small so i'm guessing a 9 is where its at but i cant find one anywhere. Does anyone know a store that caries these wrenches. 12 point internal metric wrench

 

That type of wrench (like a torx, but 12 point instead of 6) is called a "triple square", but I wasn't able to find a 9mm anywhere. Everyone sells the 8mm and 10mm.

 

Yeah, its a 10 and go to a tool store or napa, and ask them.
