spindle lock plate - front suspension

["datsun_sports" <datsun_sports@hotmail.com>]

hey guys,

I need someone to give me a judgment call. I asked the question about my
upper a-arms and dean helped me out. he mentioned the lock plates however I
realized I forgot to install them. can I back the bushings out and install
them without hurting the new parts. do I really need them?

thx,

mike
