No instrument gauge lights or push button lights - 64 Dart

I'm not sure a 64 is wired the same as later models. Do you find one fuse that doesn't have power on either end of it until the park lamps are pulled on? Labelled "inst" maybe. That's the illumination fuse.
There is a way to ad a jumper on the headlight switch bypassing the rheostat. Full on dash lights at all times. The last new switch I purchased was about $13, so a jumper may not be worth the effort.

Last night I thoroughly cleaned the fuse box, no dash lights. (everything else tied to the fuse box works) I have continuity through the fuse. I'm thinking it's the headlight switch too. Found it for $13 dollars @ carparts.com. It will be here on Apr 3rd. Fingers crossed. I contacted the guy I bought it from and he said the dash lights haven't worked in 35 years... the nice thing is no one else has tried tinkering with it. Thanks again for everyone's help.
