[V8] UFO screw

[Kneale Brownson]

Thanks, Bernie & Cobram.   The problem with a next-size screw is it comes with a larger head than the recess in the rotor.  Suppose I could take a flathead countersink to the rotor and enlarge that too, eh?
   
  I was using an impact driver (hand-held hammering type) when the screw head twisted off, unfortunately.
   
  I suppose Cobram's suggestion will help with roadside orientation.  I've got a broken snow broom with expandable shaft that I've used to apply brakes so I could check lights, etc., so I guess I'll leave that in that car instead of keeping it in the shop.

It's usually not a problem as a little corrosion goes a long way towards
holding the orientation. You could cut a piece of broom stick so it fits
between the seat and brake pedal to hold down the pedal and lock the hubs
when you have to change a tire. A flat piece on the seat end helps, you
wedge the piece in then use the seat adjustment to get a good lock. 

You need an impact driver if you want to get those hat screws out without
breaking or stripping them.
