Hard that 04 starter motor helps sluggish starting of 03 models.
Just got 03 model, stripped out to check everything, repair damaged wiring, shim valves, overhaul starter etc.Jsut started to put it back together. Located 05 starter secondhand at breakers and will buy it if I am certain it will fit. Info anyone.
cheers
