Questions: The heat riser kit doesn't include the flapper according to the pictures. Does the manifold come with a flapper and is the heat riser kit and flapper installed, or are they separate?

Questions: Hi- I noticed that the hole, closest to the firewall is broken on our jeep. The manifold is sorta jury rigged, but seems to work ok. To replace the manifold, are there just three bolts or is there a hidden middle bolt that is not showing in this picture. -Thanks Peer
