Info on straight axle for '66 barracuda project

I'm having a issue with my pitman arm rubbing on oil pan when turning left and I'm running a manual gear box and was told I need a longer pitman arm. Any one got a clue . I'm running a speedway motors straight axle setup and 360ci motor
Ten year old thread.
I would modify the oil pan LONG before I would mess with a steering system that works. Got a hammer? Or a welder?
