I think the AS spacing is the same between each hole, but the start position is slightly different so if you had a Doepfer and AS module next to each other there might be a 1 or 2mm gap. you can also remove the threaded inserts from your rack and cut them into smaller lengths to get around this issue without needing to enlarge the module holes.
