There are so many parts that are the same it probably doesn't matter. However, I would procure the components for the vehicle the engine is going in to just in case there are some differences. I would also check the mounting locations on the engine you are going to install. 6 cyl car engines of that era had a side mount arrangement and truck engines had mounts located on each side on the front. I believe later engines had both.
