How to weld OMP rollbar brackets?
 

I've bought an OMP rollbar and placed this in my car yesterday to testfit. The cage fits the car nicely, but I don't know exactly how to fit/weld the brackets on the floor, because there are these solid lines that run where the support bracket should go:

I'm not looking forward to moving and re-doing these lines... any tips?

On the left side of the car (pictured) are three lines. I guess they're brake lines, and on the other side are two thinner lines. Fuel lines?

thats the problem with the omp cages,you have to move the lines to fit them.there are box sections that get welded in place for the cage to bolt to.

I've got those box sections / brackets. That's no problem.

But how should I move these lines?
