What is the size, in milimeters, of the driveshaft flange holes on my '85 pickup?

I need to get a drill bit and my truck is on the other side of town.

Not sure if that is the larger holes, should be. I did mine with a 3/8" and reamed it out a little. actual size should be 7/16th".

I haven't confirmed these yet but I combiled this info from another recent post. Your drive shaft bolts should be 10 mm and I think Toyota make the holes 10.5mm but again I haven't confirmed this myself. When I drilled out my flange I used a 13/32 (.406") dia since 10 mm is (.394").
