Fenderwell headers too Close to Master Cylinder Line

Might want to look here http://www.forabodiesonly.com/mopar/showthread.php?t=129440 at post #13. This coupled with the right exit m/c might be a big help. My car had something similar to this done. Instead of grinding on the back of the adapter the lump on my firewall was removed. Took some trickery to get the pedal back in the car, and I do not remember waht it was. Will have the car in a few weeks can let you know then....
