 Just a word of warning to those of you that don't feel lucky. If the person
 that inspects your aircraft deems the aluminum plate and attachment method
 not satisfactory, you won't get your little piece of paper until you remedy
 the problem. My plates on both my 235 and my RV-9A are stainless steel per
 the suggestion of the local AB-DAR and nearest FSDO inspector. I know you
 wouldn't get by with anything less with either of them.
