Headers arent fitting. Power steering pump in the way. Which way do I go?

Have a 63 dart gt. Took the motor which is balanced etc... out of a 74 scamp and put it in to my 63. Motor had clifford 4bbl intake and headers. Got the motor in and doesnt look like headers are going to fit. Power steering pump is in the way. Should I put a manual steering box in the car or possibly buy a new set of headers from clifford (not sure if they clear power steering sector). I looked at the pic on their website and the new ones they have are different and have different angles from the looks of it. I have the full exhaust off the 74 also so there is benefits to swapping to the manual steering sector I think. Would save me time and money. I dont have the scamp anymore so i cant look at the differences. Pretty sure it didnt have power steering though. Thanks for any info. Its highly appreciated. :banghead:
