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
Willys Tech:
The intake and exhaust manifolds share bolts so that is correct.
