Where and how do I get bronze sleeve armature shaft bushings for a 12v starter motor for Koehler M12S?
This was easy before hitech made stuff easy.

SAE .336x.459x.346 or 8.5mmx11.69mmx10mm.
and
SAE .520x.750x.470 or
13.25mmx19mmx11.42mm
Chicom starters (2 in 2 years) are not getting it.
lol I got a headache.

Think I found them hiding in outboard boat engine parts.
