For anyone who was wondering, the Mustang was fixed by putting a new starter and cables on it. The starter bench-tested good, (meaning it spun when power was applied) but wasn't strong enough to turn the flywheel. When you put it on the bench next to a brand new starter, the new starter turned about twice as fast.
While the car was up at that shop, I had them put a new header on it, dual exhaust with dual flowmaster mufflers. I would have done it myself, except that I don't have a mandrel bender, and the don't make an exhaust kit for my car. I don't have experience in welding, so I wanted it done right.
