74 to 65 Drivetrain Swap!

After reading your original post. I see you already have a 318 and linkage shift 904 in it you are pulling out. You are swapping motor trans. and axle from another A body. It will be a direct easy swap as your car is already set up for it. On the left [ drivers side ] motor mount just put a couple washers under the one bolt that will need a small space taken up. On the right I dont recall your 318 block ear setup but you may need to cut one ear off the mount on the engine side on the mount and weld it to the front side of the mount. You may also need to grind a little from the head boss and the manifold on the left rear so you dont break the manifold when you bolt it back if you still have the rear dump 273 manifolds.
