Shannon This is just my 2 cents but I would not reuse any bolt or locking
style nut or washer in any critical area. I work for one of the car companys
in preproduction builds There has been times when a perfectly good looking
bolt etc has been reused (not company policy} and failures have occured
because the fastener has lost its ability to hold torque value. As far as
your new fasteners they should be of the same quality or higher than orginals
ie 8.8 , 10.0 metric or grade eight . Would not use grade 5 or 8.8 metric in
critical area. Other may differ but I would not take the risk for the what
you might save. Good luck
Regards
Mark Luichinger
