ElC,
My eyes aint what they used to be either, that's why I was happy to find the snap in mounting arrangement on my panel box. Reach up and release the lock clip, slide it up 1/4" and the entire block is in my hand where I can bring it out and look at it. I figure that I'm not likely to be needing to replace fuses very often with all new wiring. I can't remember the last time I needed to replace a fuse on any of my vehicles, but it's been long enough that the only replacement ones I have around are the glass tube type, and those will soon end up in the garbage can when I move my parts stash into the garage.
