Another option is to lower the center link bar!!
How? Simple, loosen the three bolts holding the steering box to the frame, and put a small shim in at the top and tighten back down. An 1/8 inch shim at the top will give at least 1/4 or more at the bottom end. This will change the angle of the pitman arm and lower the the center link bar !! I had to do this on my 74 challenger, not for pan clearance, but for a little more clearance for the Patriot Headers as the center link bar grease fitting was hitting the lowest header tube.
A heck of a lot cheaper than changing the pan or messing with the motor mounts as shimming the mounts will raise the engine and you might already be tight on hood clearance.
