out of commission, cant drive my dart anymore

As to the T-bar adjusters;
Prior to backing them off, use lots of penetrating lube, and I measure the ride height at some convenient place that is repeatable.I count the turns as I back them off until the tension is released. Then I continue to some easy-to-remember whole number.
After you get them loose, you may wish to take the bolt out and clean the threads, then slather it with anti-seize. This is why I measure the ride height before starting the job.

Whatever you do, do not scar the bar with plier type tools, the marks they leave can start stress-risers that lead to bar failures.
