Where did you get tool to open differential fluid plug?

[Thizzelle]

For large allens in tight spaces i usually end up cutting an inch or so off the long side of an allen wrench, inserting it in the plug and putting a box end wrench on it. Thats only if none of my allen sockets work, though.

this. guy at works makes me tools, he loves it. He races motorcycles just went 215mph on his at the salt flats.
