burt

I've been hunting down this vibration for a while and it is now pointing to the wrong harmonic balancer. Truck is a 91 f350 that was originally na then re motored with a promar idi-t motor. The new motor got the balancer off the old motor and now I have been told that the turbo is supposed to use a different one. Any body know where to get a new one balanced for the turbo motor? Initial findings are showing one part # for idi hb.
