The lower control arm shouldn't change anything relevant to the caliper clearance.
I believe the only calipers that have that bottom outlet were the '73/74 B bodies, everything else should have them somewhere else. But RockAuto's pictures may not show that, you can't necessarily count on their stock photo's matching the exact part number. E-body calipers have the offset hose location, as do earlier B-bodies and some FMJ's I believe.
And to be clear, it's not just a hose outlet difference. The body of the caliper itself is different, the '73/74 B-body calipers have a large protrusion on the bottom of the caliper that isn't there on the E-body calipers. You can't see it so much in the top picture, but this one makes it really clear...
I had heard of this issue before, but I ran into it myself a few years ago when I was installing 73+ disks on a buddy's car. I don't recall exactly what it was that the '73/74 B body caliper interferes with, but I know that there was nothing I had on hand (different brake lines) that could solve the issue. And to tie into the whole part number thing, the remanufactured calipers I had were supposed to be a set, but I had one of each kind.
There may be a hose line solution, but IIRC the issue is less about the hose line and more about the shape of the caliper itself.
