One combo gage backside shows lamp in 2nd from left position, but mine is a 76 with that position dedicated to cat converter warning lite. Another image shows other lamp positions, but mine has none.
Does the gas gage have aa built in lamp ? I can see nothing from the backside other than the low fuel indicator lamp., Same for the oil temp gage.
Current track 37 shows L7 fuel gage lamp, but can't find it anywhere.
