Pulled the whole cluster out this evening and cleaned and scrubbed everything up, replaced bulbs, loosened and then re-tightened all GROUND SCREWS on the backside (hoping this would fix the dead fuel gage)...

The #168 bulbs are much brighter, love it! All turn signals and lights work fine, but fuel gage still zeroed out. Oh well. Will pull the sending unit in the tank again this winter.

One question - on our 68s, what, if any, idiot lights are supposed to come on with the key in ACC mode? I'm drawing a blank now.
