duster 440 exhaust manifolds

Dude, why would you title your ad as "440-Duster exhaust manifolds" and then say your not sure if theyll fit and that you dont wanna mislead anybody? c'mon now lol !!! Did the guy who sold you the car specifically tell you they were on the 440 AND in the Duster?

If he did in fact have them installed then im interested but I need to know the weight so I can figure out the shipping to where im at... Thanks!
