Default flywheel bolt size 911 2.7engine

What is the flywheel to crankshaft bolt hole size for a 1976 911 2.7 engine?
The 6 bolts seem to measure 12mm x 1.25 but the only technical manual I have says they should be 12mm x 1.50. I want to clean out the thread holes with a tap since they seem to have loctite residue in them.
Thanks,
Mark

The bolts measure M12x1.25 Wayne Dempsey Book...How to rebuild and Modify Porsche 911 Engines is wrong as it states M12x1.50

Might be worth stopping by the hardware store to pick up one of each and do a test thread before hitting it with the tap.
