Thank you for your response. Now you have me thinking about the rattling heat riser. There is a nice appearing manifold on EBay right now, but it also includes the LH side as well for $200.00. I'have asked the guy if he's willing to sell only the RH but no response yet and of course the ad is close to timing out. For some unexplicable reason Id feel better about buying one from a member here on the FGF site.
