I might try a diy solution:
And then M5 40mm bolts to go into the Martin Ascher adapter plate.
Cant find M5 30mm spacers which would be better but M6 should be fine too with washers.
So bolting the Martin Ascher adapter to the wheel and then the SQ2 wheelside adapter with the 40mm M5 screws with the spacers in between into the martin Ascher plate.
Will let you guys know how that works or not.
