1970 Plymouth Duster 340 4-speed

Your doing an excellent job on the car,but I'd hang onto it and work on it when you have the time. Like others said your halfway done. When you are done with it,it will be pretty much a new car that you can enjoy for many years.
I too have projects going to and not a whole lot of time but I am hanging onto mine until time comes around for me to work on them.
