Just FYI... Chrysler had a problem with the 3 steering gear attach bolts working loose. So these bolts with special head also have a special thread profile that was supposed to work better. Then they started using Loctite ( Chrysler funded development of a thread locking chemical. Dupont won the contract ). Eventually, at some year model, the bolts went back to standard thread profile and hex head.
I prefer these special bolts along with the locktite.
