You can use this set-up with front drums. You would run a 10 lb. residual valve in place of a 2 lb. residual valve.
I like this design from the standpoint of it mounts in the existing holes in the frame and you don't see it once it's done. I'm assuming your reference to the American model is the one that mounts to the firewall and has a pedal that swings down?
That method would work better, but doesn't look as original!
