parking brake cable routing

Ok I have a 72 dart swinger and I bought new parking brake cables from inline tube. I have the rear cables assembled but I am at a loss on the front cable routing. The old cable is still in place but I can't see anyway possible to run it the same route as the original. So is there an alternate way to run the cable or do I have to try and fish it through the original routing. There is a hole in the crossmember next to the torsion bar so can it run along the frame rail and go through this hole and still function correctly, any thoughts or help will be appreciated. Thanks
