Stealth,i TOTALLY agree!When it comes to holding them on.I am actually talking about holding them TOGETHER,which(not being that clued up on metalurgy,or it's spelling!) doesn't seem to invoke the same levels of stress and therefore will allow a lower strenghth bolt ie SS.
Frank,i have used SS everywhere on all my Dukes and never had an issue with reaction between the metals.Maybe it's because they are not in long enough!!
