I agree with 1ownerT, get the car checked out by a competent repair facility. I've had good luck with Goodyear in my area.
And at the risk of sounding sexist, I would highly recommend you have a boyfriend, brother or Dad go in with you, as it seems all these places tend to take advantage of women, particularly if you're not the most mechanically proficient... Either way, get it checked out and fixed as you don't want to take a chance on something so important to the safe operation of your car.
Best of luck getting it fixed! Let us know what the problem was. The '79T/A is a wonderful car to drive when the front end end is tight and accurate!
