Does anyone know the specs for the hole pattern under the head on and 1100?

I have a PCNC1100 Series 2 and I want to attach a bracket under the head. I'd rather avoid drilling and tapping and luckily there are four threaded holes in the head casting just behind the spindle. They appear to be metric and I don't have the necessary tools to easily determine what thread they are and what the bolt pattern is while working upside down under the head. If anyone has this info handy I'd appreciate it.

Here is what I used when making my nozzle setup.

M6 screws part# 95836A680 = $5.61 (pack of 10)

I would ping info@tormach.com and ask them the hole pattern. They have been very fast to answer my doofus questions, and I don't have a machine yet. It has been within an hour for answers for my questions.

thackman, from my older coolant manifold thread I see that the holes are M6 and 65mm apart (X axis) and I just measured as well as I could (my own mill isn't re-powered-up yet and the spindle nose is still down on blocks) and the holes seem to be spaced 95mm in the Y axis. HTH.

Thanks for the info everyone. The M6 screws I picked up were a success. I'm planning on mounting a bracket under there for some accessories. Anyone know why there is a big square hole in the head casting? Is it for airflow for the spindle motor or just part of the casting design to reduce weight? I was planning on adding a pocket to the bracket just in case obstructing it was a bad idea.
