I have seen two styles of the 404 release. One has a green release and the mounting bracket goes across the back of the plate. The back of the boot appears to sit ontop of the bracket. The other possibly newer style has two individual mounting brackets, and so the boot would sit flat on the plate.Ãƒâ€šÃ‚Â It seems to me thatÃƒâ€šÃ‚Â the one style would actually lift the rear of the boot up some . Anyone have any ideas on which is preferable and why.
