The solution is easy.
use a 2.5 mm square spacer which supports the three tabs at the A90. ofcourse the VTA needs to compensate for the 2.5 mm thickness.
you may use aluminum, brass, or ebony.
the downside is one of those materials will sound best in your situation so you have yet another parameter to tune.
the three tabs on the A90 just fit fine with the Airline, but not much space left here either.
very tempting to comment on the dremel tool 'advise'..
