Caliper bolt thread type?

[4birdman]

I am about to put together an LS1 brake setup on my brother's GTP and I want to drill and tap the caliper bracket rather than having to sleeve the spindle. Can anyone tell me what the thread type is for that bolt? I don't have the bolt off the car yet since he is driving it, and it would be nice to have the bracket already drilled and tapped so I can just bolt it on.

Can anyone help me out?

it's M14 x 2.00

Great, thanks.

Np, finding the tap is probably going to be the pain point.

I'm pretty sure I already have one.

Yep, got one. Should be all good to go.
