Snap-on tools sells the special socket for this theft resistant screw. Or, if you are friendly with your local Chrysler dealer's service manager, you could perhaps get him to have someone loosen the screws for you. You're right, these are the original screws. They are hard as the hubs of hell, so almost any tool you try to grab them with will slip right off, as you've no doubt learned.

Must be original equipment because it's held in place by two tamper-resistant screws. The heads are tapered, with three slots, between 7 and 8 mm wide. They are not torx, and have been very resistant to my attempts to tamper with dremel, vise grip, hammer and awl, etc. Local dealer says they do not have socket in their tool box, and haven't had luck at Napa, Radio Shack. Does anyone have any ideas on a supplier for such a socket, or alternative means of removal? Thanks, Dave Morrison, 81 EFI, 82 FS EFI
