I made a switch panel out of aluminium and gave it a brief polish (a hazard switch off late model beetle, then three switches (one for fuel pump, one for windscreen washer, and one spare).
Pic is a bit blurry but you get the idea - because the original fuse box is no longer used, I thought it was a perfect spot for the switches.
Two stainless button head bolts with nylock nuts secure the panel in place.
I layed down another coat of high build primer on the sub box today...bit more filler required to smooth out some imperfections before the base coat colour goes on. You can see the recessed section for the vinyl insert.
