Mopar to fix

Which year and body of the mopar family is the easiest to get parts for? There's very little available for the A bodies before 1968. I can't find taillamp housing for a 1972 scamp which is the same as a 1970 dart. I've tried the internet. Mopar is behind the times as I can get everything to completely rebuild a 1964 - 1968 mustang, same thing for most of the gm cars. I don't know how people restore their older A bodies as there is no replacement body panels, grill parts, heck there's not even windlace available for the A body after 1969. I can get universal windlace but that cost points at car shows as the color,pattern, texture is not as factory. No console bodies for the A body mopar either.
