The JGC is a Mopar but it has a newer Jeep engine. The Jeep engine was designed with its' starter on the passenger's side. Our Mopars have the starter on the driver's side. The Jeep, with its' starter on the passenger's side, has a ton of room in the space that our Mopars have a starter. With all this extra space where our starters normally live the Jeep engineers decided to use this space for the manifold to be. As a result the Jeep driver's manifold exits where our cars have a starter. I only know this fact because I attempted, for many many hours, to install a JGC driver's manifold in my 69 Barracuda. The Jeep manifold ran right into the Barracuda starter no matter what I tried ( I also had installed the smaller later starter to increase the space in that area). If you install a Jeep motor (318 or 360) in your Mopar you could probably use the Jeep driver's manifold. You're welcome to try this for yourself but with our Mopar starter on the driver's side I don't see any way it can be done. If it could be done someone would have already done it!! On the other hand (right hand...LOL) the JGC passenger's side manifold fits like glove on our Mopars and offers much better flow. So if you can find/get a 340 driver's manifold it's a piece of cake since the JGC manifolds normally sell for $25-$40 at most car salvage yards!!!
