I think there is some thing in the tech archives on what you need to do a stock mopar change over. Yes it sounds like a cobb job and your right to park it until you get the correct safe parts on it. When you get it all back together, find a old school front end alignment guy that know how to set up a drag race car. Most shops now say we don't have a computer program for that old of a car , [ but ] we can get it close. Run from those guy's.
