I need to access power from the fuse box, there's a 8mm nut I removed, but I still can't get the fuse box to budge, I want to run a wire through the firewall to my dash, for a switch, is there something I'm missing?

I just ran a wire to my dash for my tach install. I used one of the extra opennings where the vacumn hoses go through the firewall worked great.

I need to get power from the fuse box though, so I need to run it through it, so its not being crimped down by the fuse box cover

There's info on it here if you sift through it... and while you're at it, you could always set up your lights to run as Euro Spec would (without, of course, the actual lighting element upgrade)...

Be very gentle... all those wires tied into the box and the years will make for some stiffness encountered when trying to move it. Also, there are some little clips toward the bottom of the panel that slide over the sheet metal towards the interior of the engine compartment that serve to help hold the panel in place...

Ok, it wasn't to difficult to pop it in (towards the kick-panel), so I did what I had to do.

The biggest headache of it all was pulling/putting it back in, had to use the two knobs that close up the fuse box cover to help guide it in, but its definately a "take your time" kind of thing, you dont want to break any of the plastic pieces, or break the screw that holds the fuse box in place. Its really just pressured in place.
