mounting batt fuse block? ideas?

[Garfinkles Motor Works]

I braze a bolt to the metal strip on the finder side of the fuse holder then attach a nylon block to insulate the bolt and strip from grounding .The metal mount for the other fuse relay box mounted on the finder gets an extension brazed on to mount the nylon block .By counter drilling the holes in the nylon block the nuts are below the surface and are not in contact with each other or a ground .On my car I made a plate to mount the sound system fuse and a fuse cover .I have done several of these with out any problems .
