Advice needed on installing AMD full quarter on 70 Duster

pictures of the the area of concern may help...

And yes, every quarter panel I've ever installed takes some type of trimming, modification, manipulation to make it fit and look proper.

I installed a set of quarters on a 68 Chevelle SS427 car here last year and the AMD quarters I installed required extensive work in the window channel area to make the back glass fit.

Used another set (not AMD) on a on a 65 Mustang and well... let's just say the quarters are on, and look great...now.
Not trying to scare you, just letting you know.
