Is there a problem using the 73 crank shaft? Does the TA motors have a special crank? Or do I have to find a 1970 crank? Thanks MoParts

Still, on the other hand, water is water! And east is east and west is west and if you take cranberries and stew them like applesauce they taste much more like prunes than rhubarb does. Now, uh... Now you tell me what you know.
