around $2500, remember you are going to have to replace or rebuild a lot of parts, carb, wheel and master cylinders, brake lines, fuel lines, all water hoses, heater and radiator, replace fuel pump, and maybe the radiator, water pump, clean fuel tank, you should drop the pan and check for rust caused by condensation, drain trans and rear end, you may have to replace all wiring, maybe wheel bearings, trans bearings rear end and rear wheel bearings at tleast the grease seals, and 4 new tires, it takes about $1000 to bring back to life a vehicle that has been setting that long, and that doesnt include any upholstery or paint, or window channels, believe me you can never buy one cheap enough, you have to look at it as if your just buying a body and frame
