I've never done it but my friend has one on his 99 Blazer that's been dropped 4"/6". The mechanic who did it used a certain type of drill bit made for jobs like that. I think it mentions it in the directions but either way it's a bit that when cutting sends the material back out so none winds up in the oil pan. At first he was a bit leary of drilling into the pan but with that bit he said it was easy.

follow the instructions about where to put the hole then use a sharp PUNCH to make and open up the hole then grease a TAP thread the hole and flush the oil.
