I have an Abba stand that I use on my TreK.
From memory I'm fairly sure the Abba site does not list a fitting kit for the TreK but does list one for the TNT which is what I bought. I had to modify the smaller of the two locating pins as it was only very slightly too big, the figures you are quoting (locating pin diameter 10mm and hole diameter 9.5 mm) sound about right. All I did was sit down for 10 minutes while I was watching the news on the television and rubbed the part of the pin that locates inside the hole with an oil stone, there is so little material that needs to be removed this doesn't take long. You do need to tie the footpegs back as they will foul on the Abba frame as you are lifting the bike, but no great problem.
To work with the Amazonas I think you will have to put the stand on a sheet of thick plywood or something similar to get the back wheel off the ground. I use an old kitchen cupboard door, 12 mm thick, for my TreK and I suspect the Amazonas with it's increased ride height would need something a bit thicker. But apart from those few small niggles, it works really well, is easy to use and is very stable if you need to work on the bike.
