Actually I don't know much about pulleys. I probably should not have chimed in. People seem to have a hard time when they start mixing and matching. 68 and up have a different balancer and 69 and up have a different water pump, plus two lengths of 69 water pumps? I think the answer to your original question is no. The easiest answer is to use all the pulleys and brackets that came together as a set on a specific car.
