Okay, i was able to make it happen again. Here are the steps:
install Freepbx Distro on VirtualBox 5.0 VM
BETA – 10.13.66 64 bit, Asterisk 13, normal install
server reboots
freepbx 13 installs
login to freepbx13 and install syadmin module
apply config
files in /var/www/html/admin/modules/sysadmin/hooks/ show 644 permissions as mentioned above.
rebooted just for fun. no change to permissions in the hooks directory…
run fwconsole chown and permissions are then set properly.
