If you have to run a transverse Tbar car use the newest M body you can find. The early versions has durability issues, especially in police service. I'd imagine you'd want one with all the durability upgrades, which would not be any F body.
You could very well be right. I will admit I don't know much about this era mopar. However, I will agree with someone above is I have heard about a couple Diplomats that handle pretty well.
