Engine case bushings

[searcher415]

Need to machine new engine case bushings to fit a different swingarm bolt. I was thinking making them out of 440c stainless and having them tempered or attempting to do it myself. Has anyone made them out of anything else?

make them out of steel aluminium and stainless shouldn't be put together it will cause electrolysis and corrode

Thanks for the tip. Would H13 be a good choice? I just don't want them to rust.
