Thread size?

[1983/300CD]

Does anybody know the thread size for the 12MM bolts that hold the front brake rotor to the hub?

The three choices are (12-1.25) / (12-1.50) / (12-1.75)

A couple of my bolt heads stripped out, and I had to drill them to get them out. While drilling, I smoothed off the threads at the bottom of one of the holes. I'm sure it will still hold, but I want to put some JB weld into it and retap to make it pretty again.

$185 for a new hub plate!
