front ABS sensor bolts

[Lowrider]

Hi Guys, does anyone know what size the smaller of the two front wheel ABS sensor bolts is? I removed the larger 5/16 bolt, but the smaller one seems to be a 12 point bolt, but I can't seem to figure out what size. It is rusted quite a bit and I have a bad feeling it will strip when I try to remove it. Any ideas? Help!!!

I just had to remove the sensors on my 94 lastnight. For the smaller bolt, I used a 1/4 socket. It worked smoothly on one bolt, but the second was being a pain, so I hammered the socket on and it came right off.
