So, I own this 85 Cressida wagon MX72 here.

My question is about how best to lower it. Ideally, I'd like to use these Megan coilovers; they're adjustable, they include camber plates, and they're a great value. Plus, Megan comes highly recommended by a few friends of mine.
The main problem I face is the rear suspension. I believe the coilovers are intended for the sedan, which has a multilink rear suspension setup, versus the wagon, which has a four-link panhard rod. Over on ToyotaNation, I was told that the coilovers could be mounted to the strut caps in the rear, but in all my research, I've never seen it done. The route most taken, aside from cut springs, which I'd rather not do, are Nissan S14 lowering springs with Camaro shocks.
Is there a way for the Megan coilovers to safely work in the back of the wagon? Has anyone here seen it? And if not, what else is effective?
These are the coilovers I'm talking about:
