i've done a few, but not much time to help. trust me, it's really easy. just take your time and follow my suggestions above and you should be good.

also, if you make the hole a little larger than the lock core, you can align them easily. it also helps if you slightly bend the studs to meet the hood at close to a 90* angle. mount the studs before you do any drilling, bend them to the curve of the top of the hood, put some grease on the tops of the pins and lower the hood down to mark where to start drilling with a small decently sized bit to work from.

the first one will take you a little bit of time, but the second one will take about 1/4 of the time.
