M970 xtr cranksets troubles

[Will78]

Hiya folks .
Right so I have a xtr m970 chainset with a sm bb-52 68-73 mm bb but even the the 3 spacers supplied still have roughly 3mm lateral movement.
Please help
My frame is a 98 Hei Hei

Kindest regards
And thanks in advance

Worn splines?

Re:

Doesn't the Hei Hei require a fancy Mavic floating bottom bracket due to the tapered facing on the frame? Another standard that never became a standard!
