Re-ARM mounting measurements

What are the Panucatt Re-arm mount measurements? Does anyone happen to have a schematic image? I have looked all over the Panucatt website and the internet but I can only find electrical schematics. I am wanting to design my own custom mount however I need the measurements for the mount hole spacings.

The re-ARM apparently has the same footprint as the Arduino Mega 2560. Here is a link to its dimensions:

I thought this as well, however, when I match other Re-ARM mounts with Mega 2560 R3 mounts, the screw points do not match up. 2 of them on 1 side of the Re-arm match up slightly close, however it would still put some stress on the board if I should use them.

Gotcha. Glad you checked before starting your design.
