Well I did re-arrange a lot of stuff to interwork with the 200B column switchgear I fitted, internal reg. on the alt. and thermo fan etc.
I retained the OE glass fuse block but changed the linking on the back of the fuses.
I fitted a few relays to unload the lighting and ignition/start circuits in the switch gear
A very good quality blade fuse box is available from Hella P/N 8723
It has 12 fuses, 4 in one feed and 8 in the other, ratings determined by you.
It is only about 50mm x 60mm so it could fit where the old one was or be moved inside the cabin.
Not cheap though
You may be able to pick up a fuse box from a late model wreck.
Get the connectors that plug into it as well.
