Since I recently ran into the issue of foil and board compatibility, see below my findings. I did not find a single good source for that information.
Please add additional boards / foils if you have info!
Information refers to distance of baseplate screws (mm) and screws size. Track refers to variable lengths.
Slingshot Foil Baseplate: (multiple holes) 90x120, 90x140, 90x160; M8 screws
Naish boards: 90x140 or 90xTrack, M6 screws
Nobile Boards & Baseplate: 90x165, M6 screws
Shinn Jackson Board: 90xTrack, M6 screws
Slingshot boards: 90xTrack, M8 T-nut and screws
Liquid Force boards: 90xTrack, M8 T-nut and screws
M8 baseplates can be combined with M6 boards.
