Another question setting up the V6, I have pulleys I bought from a member. The fan pulley is 5 inch diameter and fits water pump fine but the 5 ⅝ inch pulley for the harmonic damper has correct 1 5/16 ID but a bolt hole circle of 2 inches. The harmonic damper on the ’86 has a 2 ⅝ bolt circle. Do I have to find a Mustang II damper or is there a different pulley available to fit the ’86 damper? Also do I have the right diameter pulleys?
