Just went and had a look through our old big block saved file folders, here are some pictures showing the mounting orientation of the BBC arrestor tube assy on a few 72 big block trucks, I wouldn't overthink it too much as we've had originals come in mounted both ways over the years. The last added picture is showing the overall height differences between the early and later style air cleaner extension/risers. Mel
