I am running a Holz skid on my 99 rmk. Im looking at my options to go bigger than the 144 I have now. I know I can buy extensions but I am thinking about going with a set of 151 rails. The Holz kit says it will work on 99-01 rails. Will newer edge rails work or are the mounting holes different from 01 to 02? And does anyone have the length of 151 rails? Any help will be greatly appreciated...
