Larry,
There are several aluminum components--shocks, carbs, thermo housting--on
my Austin-Healey 3000. I have had success using hardened ("grade 8") washers
under the bolt heads to securely "clamp" the aluminum component (especially the
shocks, which are known to work loose). I don't believe in using lockwashers,
because they dig into the aluminum and can loosen.
If it's a critical component--like the shocks, which in the front form part of
the
suspension--I use blue Loctite on the bolts and torque according to bolt size.
