gearing up to take my front wheel off (2010 wide glide) and have tire changed. in checking to make sure i have tools i need, i can't figure out what size the axle cap fastners are. they look like hex type, but I can't find american or metric that fits snug...am i way of base?. they didnt look like torx, but lighting isnt the greatest in my garage. I have the manual, but i don't see in there where it specifies size, only torq
