it would be great if you could find someone's old mopars to take a drive in to see if prefer the PS or Manual steering. the PS of that era lacks road feel most would say, depends if city driving or country driving as to what you might like??. me I have always preferred MANUAL even in big block cars..
I think we all pretty much agree it is your car. you need not apologize to anyone do what you like with it. some will see you work and love it, others not. so is life!!
