I'll see what I can dig up re pictures of my old setup. But they were fixed. Adjustable yes, but only with a few minutes and a spanner.
I'd also not recommend fixed backs (or at least not fixed in the car) if you still drive the car on the street a bit. You give yourself a massive blind spot as it's really hard to look over your shoulder with them (was with mine anyway).
That said, the Velo Podium II I had was the ducks guts. Make sure you sit in the seat though as they are all different. Personally I can't stand the Sparco's. All too narrow through the shoulders for me.
Couldn't you just look into having new mounts made for the seats you have to drop them down a bit?
