that is great work. if I was to choose a geo, it is model of engine in photos. great find. I see the back end has high fuel mileage physics. there is even special tires for this. (thicker "edges"). The egr..if legal where you live, block it off and conform vacuum valves and carb to not having it...hypermiling begins there, and that also stops strangeness on body and exhaust.headgaskets stay sealed, studs stay studs, pipes stay pipes, paint stays paint, tires stay tires...and the cabin is a natural cool and odored by nature, no strangeness...and of there is a leaking acetone truck in front of the car to suck on..guess what? it is no longer A BOMB waiting to happen.
