new to belonging to a forum website. I was raised by a Mopar fanatic and love seeing and hearing stories about them. I will be advertising parts for sale that my dad and I accumulated over the past 40 years. One of the parts is a BB Manifold 2863900 nos. been sitting on a shelf for as long as i can remember. I've been told it's worth $ 100 to $750. what's a good asking price?
