71 dodge demon headers

Hi everyone I own a 1971dodge demon 340 real h code car. I have all the front suspension out of the car and power steering gearbox . Along with steering column out. I bought a set of ceramic coated headers from summit. I had the gear box in but took it out cause I couldn't get the header in . But now the header is in and can't get gearbox back in. A bodies with power steering is a real *****. Anyone have any ideas.
