Well to help out all of you who have enquired - here's the final results and some closer pictures of the fuse upgrade
First, a gratuitous photo of my car...
The trick with these fuse blocks is to replicate the terminal joins at the back of the fuse blocks just like the factory ones - sorry I didn't take any photos of the wires I soldered at the back to make the correct circuts.
I can't seem to find a brand for these items other than to say they have 'made in china' on the back. I found them at the local equivalent of your 'pepboys'.
Also - check out the alloy trunk guard thingo I reproduced to replace the crappy cardboard original...
