It's a bit funny and requires some work but I use the AE ones for the tc 6.1.
The spur it self is a little the thicker but its the thicker inside part that's the problem. I used an over size drill to cut away some plastic so that the counter sunk screws fit nicely instead of the button head ones.
It can rub a bit in the top chassis plate but a bit of filing solved that problem.
I can't get the proper spurs so this is a great alternative for me.
