i used AMD full quarters and ran into fitment issues at the top door jam. i think that is common on these as my friend who just got his duster done had the same issue. How ever i did mine when they first came out so they may have solved the issues.
but never the less i solved them on mine by cutting a chunk off my old one and fitting it in.
if you search the link below you can look at the pics of how i fixed mine.....
5.7L hemi Duster/resto.
