The running boards on my 99 670 X are falling apart, both are cracking from the outside in, and are getting worse! the rivets and plastic grips on the runner's are just braking off. Where can I get a new pair of better, posibly wider aftermarket running boards? I see some for polaris but now skidoo, im tired of patching the cracks and snaps and need new ones. If anyone has a link or has replaced them please let me now, thanks alot!!!
