OK...So I have a 149 with a 38" deck (not sure it's the origina deckl) and one of the spindles is toasted and the other two are a bit noisy. So what I need is the part number for a whole new spindle ass'y for the far right blade and new bearings for the other two spindles. Can anyone tell me what the part numbers are? I tried to find a serial number on the deck but no dice. It's been painted over about a million times. Thanks in advance
