[Healeys] Keeping rear shock bolts tight

[Oudesluys]

As Mike Salter mentions, it is not a question of nuts working loose, so 
tab washers and security wire won't help much. The material is deforming 
thus creating play, not because the nut/bolt is turning. When working 
with aluminium alloy it is always important to have the mating face of 
the body machined, a large hardened and machined washer is fitted and 
tight fitting grade 8 or higher bolt and nuts are used.
