Simple question on M1070/HET

What size Allen is needed for the diff fill plugs? It's metric but if someone knows off hand it would help me out.
Thanks

didnt have an allen big enough to test right now. but measured it with the good ole digital caliper and it comes out to 12.24mm. i think it would be safe to say 12mm should get the job done.

this is on a 2000 year model

That makes sense a 10 was too small but the biggest I could find. Thanks for the reply "armybra" and if ya do figure out what size it takes I'd appreciate it so I know what size to buy or borrow.

12mm fits nice!
