1960s 4 amp instrument panel light fuse - 68 Coupe DeVille

[chrisbutnut]

The fuse for the instrument panel lights is a 4 amp fuse (according to the owner's manual), located in the top left spot on the fuse panel.  This fuse is shorter than the other ones.  Does anyone have a spec for this? 

I found these, but am not sure which is correct:

You have either an AGC-3AG (Automotive Glass) or SFE6 (Society of Fuse engineers), the AG have a third letter while the SFE's have a # they identified the size "L" of the fuse the AGC/SFE6 would be ¾" "L".

You may need to validate the "L" of you fuse holder.

Good luck..!
