Nothing about it is very difficult. The most time consuming part it removing the stock bumper. Installing the new one is simple. You need a helper and a floor jack is very helpful for adjusting the fit.
If you want to remove the stock bumper before you come, I'll install it for free, or for $20 we'll do it start to finish.
