A Well-Preserved Solar Gold 79 Trans Am With A T/A 6.6 and a 4 speed manual transmission. The T/A 6.6 400CI Pontiac engine is the most desirable engine to have. The car has a 10-bolt rear axle with a 3.23:1 ratio rear gears. This is a very original car with factory cold A/C, tilt steering wheel and brand new tires on color matched honeycomb wheels. The radio has been updated and sounds great. The Trans Am has established itself as a permanent American icon and this example is one of the nicest on the road.
