[Healeys] Stripped shock mount nut

[richard mayor]

Belleville washers are not going to help keep shock bolts tight. Proper
tightening, using flat washers, will do the trick.  It is the stretch of the
bolt (tension) that keeps things tight. If a bolt is coming loose, a split
washer, or spring washer, or belleville washer will not save the bolt from
getting loose. Use propert torque (tension) to do it right. If it is in a high
vibration environment, then use locktight and then torque it properly.
