Yes, should be hardlines all the way. Probably was a manual and they put in an automatic. I did that on one of my Dusters as well. The manual the car was born with was worn out, and I was on a budget, so traded a guy who owned a boneyard some parts for a used 904 transmission, linkages & cooler lines. Went to the local transmission parts house and bought a torque converter and rebuild kit. A few days later I had a running rebuilt transmission that I put a ton of miles on as my family car. Now you can pull the floor shifter that is in there and replace it with one that would look nice. Sounds like a nice project car!
