Just thought I'd bring some closure to this one.
I know you both said it was probably ok, but I just wasn't happy and had to change it.
Not just because of the cables touching the rail, but also because the plate itself bowed significantly when I applied the handbrake, and would have got in the way of where I want to bring the brake and fuel pipes through the tunnel.
Here's what it looks like now, and this time I checked the cables wouldn't touch the rail before I welded it in place!
