What do I do, I cant get rid of the parts. Need the money??????

I am trying to get rid of my exhuast and my intake but I cannot seem to do it. Where can I take it, because I have been so hard to sell them.
Its a slant six one barrall intake and an exhaust..somewhere in the early 70s.

I am intrested in the intake.
