I just received my hitch #24792  and the installation instructions say no drilling required but it also says enlarge existing hole in both frame rails. How can this be done?

Step 2 on the installation instructions say to enlarge the exisitng hole in both frame rails to allow access for 1.00 X 3.00 spacers to be inserted as shown in figure 2. 

You can do this a couple of different ways. You can either take a rotary tool to work out the side or you can take a standard chisel and do it that way as well.
