I was following your logic until you mixed the anodized word with stainless.
anyway, if the 55 had stock discs than a prebent kit might apply but in your case how do you know a generic prebent system will work for your aftermarket setup? personally I think it is a leap of faith for you to believe that a prefab will work out.
if you have time and are not intimidated by the job, do it yourself.
da.
