Subject: Re: [Saab_c900] Wheel spacers for use with Ronal/Shelby wheels?

Grind away! Try not to get them too hot, though, to maintain the heat treatment. Dip them in cool water periodically while you are doing this. If you have a friend with access to a lathe, that would be better. 1mm is nothing. Take 2 to make sure you get a good clamp.
