In the '70's I put a '62 Dodge 318 Poly in a 48 Plymouth. Real backyard engineering! We found out the exhaust manifolds were interchangeable left to right and upside down! I put two left side manifolds on upside down. That took the exhaust straight out over the frame and out the fenferwell. I tilted the steering box down slightly in the rear (poor solution, DON'T DO IT!) to clear the engine and used a u-joint mating the steering shaft to a Chrysler tilt/telescopic column. The next owner claims he fixed the steering box, but he sold it before I could see what he did.

Good luck. It is refreshing to hear someone is putting a MoPar in a MoPar instead of brand X crap.
