I know everyone sick of these threads. But i have a 05 rmk 900 on its way, i dont know which drivers i need from avid or wahl, i've looked and have an idea but cant be sure on what all fits. Is there a way i can install this and not cut my rails down? any options are great, as am settign this up as a back up only. Which brand drivers are better, can i find used anywhere, (checked ebay/CL) thanks for the help.
