Idler arm hits on header

I have a 72 dart and had the same headders and had the same exact issue. We had new rubber mounts, and everything. Long story short I had to take it and get a section cut out of one of the tubes and the guy rerouted it. They were a pain but they sound great, but I wouldnt go with Hooker again.

Did you have to weld in any extra length to make it work? Or was just rerouting enough? Did you have to modify just the one tube, or did you have to hack up more than one to make it work? I'd love to see a picture of that mod...
