Docford -- I'm uncertain what to advise for the pinion angle for the car you describe. I believe the Mopar Performance Chassis book, etc, advise how to do this.... you'll probably need an angle gage. (I had a racer-pro (Jim McKamey) do mine as I was also having the entire suspension balanced... back in the mid-80s.)
