Stop in for a cup of coffee

So I know this has been a topic on here before but I need some pictures of exactly what some of you have done to compress the 5 mph bumper shocks. I had the boy drill holes in them near the back of the brackets...expected oil to be in there and, there wasn't any. Did I have him put the hole in the wrong spot? I have also heard of taking the guts out of them?? Not real sure how ya do that?
