That worked, and actually was helpful because I had to wedge my rear header up in the gap above the sway bar while I slid the front header in...then wiggled the back one forward and up into place. Very annoying, but the sway bar held up the rear header when I ran out of hands. If you were replacing with OEM manifolds, you could get the rear on first then slide the front one by it as is Bentley procedure. But my headers have the collectors way closer to the sway bar and low...right above it, so you can't mount the front manifold on the studs and get the rear one on if it's not already above the front collector.
