Thread size and pitch for power steering pump

[wee-jo]

My power steering pump fell of and stripped the original thread holding it in place. Does anyone know the size of the thread and pitch that holds the pump on so I can have a bash at re-tapping it?

5 bolts involved in the power steering set up, 3 of 1 type, 1 each of another, can you put up a pic of which one?

You could get the size and pitch of the bolt that fell out as well.

Sorry, I can't get a pic up just now.

The bolt fell out as the car was moving. Just thought someone might know the sizes of the top of their head.
