k-frame holes dont line up
I was talking about this at work today. I do this stuff for a living.
What we would suggest is putting the old K-member back in, blocking both rails and doing a downward pull on the damaged k-member.
When you hit the rock the k-member pushed the rails out and more than likely rolled them a bit.
I would not repair this at home.
2.5 Hours to set up on the rack
3 Hours to straighten each rail
About $500-600 to get it fixed correctly.
