410 Diff screw question

[HyperDunley]

My new 410v3 arrived yesterday and reading through the manual it says you need a 1.3mm Allen key for the diff screws? If this is correct, where would I find one if these, as it seams a really odd size?

Any help appreciated . Really looking forward to building this...
