Rear Swaybar options w/ RMS StreetLynx

Any of you cats running (or know somebody who does) a RMS StreetLynx 4-links with the perches moved inboard for bigger tires w/ a rear swaybar? If so, what are you/they running?

I have a 66 Barracuda with RMS front and rear that's been mini-tubbed with boxed-in frame rails. I want to run a sway bar but since the spring parches have been moved inboard so FirmFeel (frame hung) is out of the question unfortunately. Hellwig looks like it's close but the 90 degree shoulder looks it might be very tight against the springs of the coilovers. I measure ~26.5" between the coils of the coil-overs.

I'm open to ideas and suggestions.
