Which shims? They start small and get gradually larger. The largest ones OD is .670" Not sure about the ID. Corrected .240" ID.
04-05/600-750 Showa's use 11mm I.D. I'm pretty sure the 03's use the same size. Sorry I can't give a better answer than that.
Crap!! TWF2 is correct!!! I read my caliper wrong. Sorry about that FatCat. Hope that didn't cause any problems.
