Yeah and looking at installation instructions for stock E-bodies, it looks like the bar mounts further back on the K-frame than for B-bodies.
My mounts are directly underneath where the strut rods poke through the K-frame; E-bodies are a fair bit further back, so an E-body bar will be too short.
If I make the bar parallel with the strut rod, there isn't that much reach between the eye on the bar and the mount on the arm - if I could just get some kind of heavy-duty double right angle link rods, or anything to make up the lateral difference I'd be fine. Does Speedway or someone stock links I might be able to adapt?
I'm also wondering if I could adapt 73-74 style clamp/rod style sway bar mounts and use the rod end to mount to the arm:
