Default Lycoming alternator bracket bolt torque

Hi guys, did you ever find out what value to torque the two bolts that hold the bracket to the engine for the alternator? My engine is an IO-540. The bolts that I have are 1" long and 3/8" x 18 thread. I would guess about 15 -17 foot pounds. I'd sure like to know for sure though. Also, I would probably use either blue or red locktight even though these two bolts have a two piece washer (they both go through two seperate holes) and it gets bent over as a locking tab.
Thanks, Tony
