What interchages on 63-66 dart

I am using 66 Valiant 2 door sedan doors on my 65 Dart wagon BUT am also using the 66’s B pillars as well in my wagon’s conversion to a 2 door panel wagon (or sometimes called a sedan delivery). 66 A Body bucket seats are several inches narrower compared to 63/65 buckets with the tracks different as well. I am using a complete 66 Barracuda in my conversion as well. Bench seats are interchangeable. As 66Dvert mentioned, each year front end sheet metal is unique and can be swapped if everything is used. Doug Dutra on slant6.org swapped a complete 65 or 66 Barracuda front clip to a 64 Dart 2 door hardtop.
