there are also a couple places online that specialize in armature bushings. I came across them earlier today looking to see if I could help. Looks like the way you have to get them for the starter otherwise is buy a bendix or starter repair kit - which were like 3/4 the cost of a new starter. One place on ebay was selling just bushing but they didn't list your starter specifically. Making matters worse, Jacks shows that the model number you listed was used on 20 or 30 different pieces of equipment and each manufacturer has different drawings. Without knowing what it was specifically in I threw in the towel. Good luck.
