Default Mac long tubes

i have a set of mac long tube headers that when i replace my steering rack i was going to install i was wandering if anyone has them installed and if so can they post up pics, i know they used to be on the car but someone swapped them out for bbk shorties i am concerned about the ac line that runs near the headers and the steering shaft.

I have 1 3/4" and the shaft runs through the primaries. I had to use a mill to notch my Flaming River shaft to clear

I "think" the auto headers have a farther distance between the collectors. Don't quote me on it but I think they are like that to clear wider Auto transmissions.
