Buying My First Muscle Car 1973 Duster 340 Interior Pic

For 5K its probably worth buying. Do you know anyone who is knowledgeable with mopars that can go look at it with you? See what kind of rear is in it, transmission and check the engine numbers. It could be a 273, 318, 340 or 360. Without checking the numbers there is no way to tell. Its probably not an original 340 car but who cares anyways.
Look at the side of the block above the starter and it should say 340 there in big letters. You will need a flashlight and have to look from the bottom up. There are numbers stamped on the front of the engine but they are usually difficult or impossible to read due to grease and paint.
In 73 a 340 car would have an 8 1/4 rear and a 727 trans.
Get the car running and drive it for a while. Fix what you can without taking it off the road. Then one day you can pull it down and do a full restore if you want. If you jump right in and pull it apart it will likely never go back together.
