Need steering suspension help from the Bada$$'s here

well i am deep into my new project and starting putting it all back together...when i bought my 73 dodge dart(made jan73) i discovered the steering was hitting the headers...you can see in the first pic that...well i discovered other issues like the motor mounts destroyed and engine wasnt even seated in the motor mounts...well since then i have replaced the motor mounts with proper ones and they are torqued to spec...i replaced the oil pan with a new one but it was shaped exacly like the one it took out....The car had generic headers so i bought a set of doug long tube headers and wrapped them before installing...i have replaced all the bushings and ball joints and am at the point of doing the tie rods, idler arm, and pitman arm...well i discovered in this journey on this car the engine had been swapped from a 318 to a 360 (1980)....well i installed the idler arm that i ordered the 73 and discovered it was pointing differently and is sloppy mounting to the frame...i went to install the pitman and it just slid on and was the wrong size....well it seems my car has a steering gearbox from a 72 ...you can see in the pic of the pitmans they 2 are also shaped dif...so i need help figuring out with i need to clear the pan...i know the centerlink when attached is flipped the wrong way for me to have clearance...so any guidance would be greatly appreciated.
