Found my dads original 1971 duster!

Lets see how bad it is.
The engine compartment harness takes a beating from the heat and outdoors.
Inside wiring often is in very good condition.
If you just need some plastic connectors, most can be bought used or new.

Perfect. Thanks! Here are some pics of the fuel gauge. I just took it off. It smells very badly burnt. If I shine a light in the small open space at the bottom, it looks like a burnt coil in there. Hard to tell for sure though. Can this be taken apart without damaging it??
