Why?
I think a few people have modded the exhaust enough to run a stock power steering box, but I can't remember them off the top of my head, it's been a while. I thought some people had tried either with the truck log manifolds or maybe the SRT8 Jeep "shorty" header style setup. Pretty sure there was someone else who made their own header and got it around the box, but maybe I'm just remembering what I want to remember and not what's actually happened. I tried to stay low buck, so I just swapped to manual, which isn't too bad aside from parking lots. I just wish the setup felt tighter like rack and pinion. No amount of adjustment in my old components will get me anywhere near that.
And just because you swap the engine doesn't mean you have to go the full 9 yards on modernization. The engine is the only real new tech I have in mine right now. Still have an old A833 four speed behind it and an 8 3/4 behind that. I have some buckets out of a Viper in the car, but only because they came with the car and the factory style buckets were trashed. I just see it as a powertrain upgrade, doesn't mean the rest of the car has to lose the flavor. Mine actually even looks old under the hood to some degree. Put a carb style 4 bbl throttle body on it since I sold the stock intake when I went carb to start with. Still has the classic air cleaner look which actually makes the hood scoop more useful. I never have liked the new front mount throttle body look in old cars, just doesn't fit right.
