I use the lower front wheel arms. I'm not sure if that's what they are called? Appear to be aluminum. They have a large oblong hole where I put my hooks. I use safety cables instead of chains. Just in case you're not aware, when dolly towing the Bolt, you must disconnect the 12V battery while in tow. If you skip this step, the car's computer will automatically engage the parking brake as soon as it detects wheel movement. With the rear wheels locked, you'll destroy your rear tires and likely catch them on fire if you fail to notice. Since I tow mine a lot, I installed a quick disconnect knife switch on the negative pole of the 12V battery.
