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?

On the rear wrap a chain around axle and the suck the rear bumper forward with a Come-A-Long compressing it. Take a 3" long 1" Strap iron on each side and bolt it to the sub frame bracket, as there is already a hole on the bottom side of the chrome bumper that can be used.

For the Front bumper you reposition the bumper brackets at the frame rails moving them back 1 1/2" and drilling another hole in the bumper brackets to fit the stock hole positions in the frame rails.
