I have a 74 dodge one ton 318 c.i. with the wrong drivers side exhaust manifold. My question: will the manifolds from half and three quarter ton fit ? Also does it matter if its a 360? I think the years that will work are 68-74. Is there no gasket of any kind between the manifold and pipe? Now the clutch: It was supposed to be new but has a bad shimmy when you release the clutch. I think the guy I bought the truck from said the disk might be a little tight on the shaft. Any thoughts?
