Well some good news. I found a hardware store that has long bolts, so I bought a few of them to test bolt length. Unfortunately they are not hex head. But those will come later down the line. So I put the rotors in my sandblaster to clean them up a bit and lo and behold some numbers appeared. 991.351.404.01 09 04 13
Not sure what the 09 04 13 mean but the other numbers link up to a 911 front rotor 340mm x 34mm. So I plan on spending some serious hours in the garage tonight because I have no life. The saga continues.....Can we fit bigger rotors on the S for cheap.

Thanks Markus and Husker for your help. Whats the going price for a set of base calipers
