After inspecting and cleaning up everything it was decided to only replace the brushes and bushes. The bushes can be removed with socket and a hammer. The bush in the nose of the starter has a cap which can be carefully knocked out with a 1/4" drive extension. A little heat on the alloy nose will help remove the bush. 2 of the bushes are crimped on and can be carefully uncrimped and the brush removed. Take the parts and the identification plate on the field winding and the vehicles chassis number to an auto electrical shop and they should be able to match the pars up total cost should be around $20-$30.
