440 a-body manifolds

I have literally inherited a pair of exhaust manifolds off a '69 Dart GTS 440 car (along w/some other car parts). My grand uncle's hot rod buddy told me that they came off my uncle Dave's car that got rear-ended heavily in the late-70's (the trunk panel was 6" from the package tray). They are in nice shape; the heat riser needs a spring and the other side has a repair in the cast iron that is only visible on the interior. I was thinking about selling them because I don't think I'll use them...any idea what those would fetch? I could get the casting numbers and maybe snap a few pics during this week (if I get the time, my uncle's house is about 80 miles east of here and I'd hafta get the key from my mom who is the executor). :salute:
