Doug,  Have you checked the fuse block for rusty or damaged wiring.  I had a 
very rusty '66 Convertible that gave me similar problems.  The fuses would 
fail from overheating at the cap--not too much current.  The fuse clips (metal 
clips) were very rusty and the resistance heated the fuses up to the point that 
the interior solder connection failed--not the middle of the link.  Another 
car had damaged wiring on the back side of the fuse block that allowed current 
to flow where it shouldn't.

And by the way, the infamous LM dash ground strap causes all kinds of 
problems with the dash lights if it doesn't make a clean connection to the dash 
frame--the current will find a way to other grounds.  That's the bottom dash screw 
to the right of the steering column.
