Well it only took me an hour fifteen by myself to slap on the bumper.
Calmini supplies you with 6 bolts to replace the three flanged part that holds the stock bumper on. Problem is that Calmini's holes are to small after the bumper is powdercoated and claear coated!!! So I reused the three flanged bolts, without problem. Everything else bolted right up using there hardware. Gordon/Warmonger got a good right up on it on his site so I won't carry on! I also had it Rhinolined ($50.00) on top of the bumper. Otherwise you have just a smooth slippery surface if it is wet out!
Here are a few pics of it though!!
