Is there a after market harmonic balancer for the ea-ed series?? or can a el harmoic balancer fit? i know ill have 2 go with the serpentine setup but i dont want 2 use aircon so will a shorter belt fit?

you can buy new balancers off ebay, nuline is the brand, or go to your local repco. but yes if the ef-el balancer is used then you will have to use serpentine belt conversion.
