Are there any compatible L brackets for any of the Nikon F cameras?

So I ordered a sunywayfoto universal bracket for my Nikon F without too much thought. Well it fit fine, but then I realized that I can't change the film!

Then I thought, well, maybe I can just get an F3 but then I thought that the bracket might intefere with the swinging back.

So my question is:

Anyone use an L bracket for any of their Nikon F's? outside of the F6 and the collector cameras (titanium F3) most nikon's are not too expensive so I do not mind getting a new body just to use an L bracket.
