I would start by getting the rear antisway bar and seeing how this
changes your setup. I am fairly sure this is standard equipment on all
83 TQC's? Maybe a previous owner removed it?
That's not quite right. My 82 has it, but there was, i believe a
mid year change during the run of 83's. Below some number they
have them. People on the list say it is better to have them,
and wonder why they removed them. I think the answer is that
when they designed the 4000q, they had a higher volume, lower
cost, compatible part, and when with the cheaper parts.
