Mark, this may be too obvious but have you contacted AQ?
If they could not help, you might try Sumiko. Their Premier arms (long discontinued) came from the same OEM. I have a FT-3 and while the weight/type of damping fluid is not specified, instructions say to experiment with the amount of fluid to achieve proper damping.
If this too fails, I would contact Jelco in Japan, the OEM.
Good luck.
