Replacement for fuse block terminal

I have 3 spare fuse boxes. They vary over years and models, especially the labelling (gets hard to read anyway). In most, the center position is blank (no copper clips), intended for options like a spotlight. My favorite box is from a 65 Fury (recall) that I put in my 1964 Valiant because a metal mounting stud than "screw into plastic hole" of others. I have found many 1960's-style electrical connectors in 1980-90's Dodge motorhomes, though can't recall if the cabin fuse-boxes. It seems they either didn't want to redesign or used up spare parts in the motorhomes. Grab a harness next time at the junkyard for many good spare connectors.
