Markus,
You can use the following coordinates for the vent locations:
X = 1708 in
Y = +23/-23 in
Z = 342 in

Thanks a lot for the quick reply! I also need the z-coordinate as well as the (x,y,z) location of the venting hole if possible.
Thanks!

Thanks a lot for posting! I am still unclear where exactly the reference point for the simple model as well as the venting hole are located. If you could post the exact coordinates that would be greatly appreciated.
